Web Hosting - Domain Name Changes and How They Affect You
New domain names are registered all the time, and ones previously registered expired. Sometimes that's the result of simple neglect. The owner of the name chose not to renew his or her ownership, so the name became available for someone else to use. In rare cases, a highly original mind managed to think of a new one. In the other common scenarios, someone chose to just let it go or sell it.
When you choose to change your domain name, there are actually two separate steps involved: releasing the old name, and adopting the new one. But, just as the postal system can have difficulty forwarding your letters when you change your personal name, changing your domain name brings certain difficulties.
One of the most prominent is the fact that any name change requires a change to thousands of DNS Servers around the globe. DNS (Domain Name System) is the set of software/hardware components that allows domain names to map to IP addresses. IP addresses are what are actually used 'under the covers' when one computer communicates with another.
Note that there isn't always a 1:1 correspondence between a name and an IP address. One IP address can serve multiple domain names and one domain name can have multiple IP addresses. For the sake of simplicity, we'll stick to the common case here.
DNS servers around the world maintain internal databases that match the name to an IP address. Not all servers have all pairs of names/addresses. A series of complex routines allows a request to be forwarded when the particular DNS server doesn't have a needed record. When you acquire a domain name that used to be associated with a given IP address, the odds of you acquiring the same IP address are extremely low.
In the unlikely case, for example, that you acquired the domain name yahoo.com, you would almost certainly not get the IP address that was matched with it (unless you bought the Yahoo! company). So, as a result of the change, the name/IP address pair is no longer what it was.
A similar circumstance exists when you retain your IP address, but want to change the domain name associated with it. In either case, the pairing has changed.
The catch is this: when the change takes place, those DNS databases are not all updated instantaneously around the world.
Even apart from the limited speed with which computers and networks operate, (and neglecting the human factor if/when the change is made manually to more than one server) the reason is something called caching.
In order to communicate efficiently, DNS servers are designed to assume that changes will be relatively rare. Just as with the postal system, you don't move your address or change your name every minute. Since that's true, in general, the name/IP address pair is cached. A cache is a set of stored information that is reused so that fresh information doesn't have to be communicated with every request for a web page or data.
A chain of DNS servers pass requests to the last known address. There is usually more than one system between your computer and the server you want to communicate with. Most of the time, that's your current name/address. When you change the name, that pair is no longer valid. In order to propagate the new name/address pair (so the terminology goes), that cache has to be refreshed.
Something similar happens when you establish an entirely new name. That name is first associated with an IP address and that pair has to be communicated to DNS servers around the world in order for you to be able to reach any one of them at random.
But DNS servers don't do that until they are requested to do so by your action of asking for information from a remote server. Because of that, but chiefly because of caching, it can take quite a while for the new pair to become known around the Internet. Caches can expire and get refreshed in a few minutes or a few hours. It varies.
That time can be as short as an hour or less, if the path between your computer and the web server is very simple and only one DNS server needs to be updated. Or, it can take up to 48 hours or more. Though the 'official' range is often given by registrars as 24-48 hours, the average is closer to about six hours. But that's an average. The actual time in any given case can (and does) vary widely.
In the meantime, a number of effects can occur. The most obvious is that, since the name/IP address pair can't be resolved properly, you don't reach the server you want. Your browser points to the old one (in the rare case it's still accessible by that name and address), or it simply reports there's no such name at that address.
So, when registering a new name or buying an old one, you should establish the site, but not advertise it for at least a couple of days. Better to wait to get visitors than to turn them off by being 'not at home' when they call.
How to copyright music How to Copyright Music for the Beginner For those wondering how to copyright music the answer can be both long and short. The first thing to remember is that most people are confused about exactly what it means to actually copyright music. Music is actually copyrighted as soon as it is presented in a fixed form. It doesn't really matter whether that fixed form is as written sheet music or as a recording. Most people are looking for solid legal protection and while a copyright is good to have, it is essentially worthless unless you've actually gone to the effort of also registering your copyright. Rather than asking 'how to copyright music', perhaps the better question would be 'what do I do now that I've copyrighted my music?' It doesn't really matter what you call it unless you're moving around in legal or industry circles I suppose, but I've always felt that it's a good idea to have a clue about the process in which you are embarking. Now that we've answered how to copyright music, it's time to move on to the real issue, which is registering your copyright. Music is registered through the U. S. Copyright Office. You will need to fill out an application, pay a fee, and provide a copy of your music. As far as government dealings go, this is one of the least painful. Even the fee is marginal when you consider your 'hopeful' future profits and royalties. All that aside, there is something that is massively satisfying about knowing how to copyright music and having your first piece of music registered. Music is an art form and the ability to write music is nothing insignificant. It is a real talent that is actually quite rare. Many popular musicians today use music that has been written by others either in addition to or rather than music that they have written themselves. Even if you aren't a talented performer, it doesn't mean that your music will never be seen or heard or that you should not bother learning how to copyright music. You just might find that you are more in demand for your particular talents than you would have ever dreamed possible. The big thing to remember though is not to sit around wondering how to copyright music but to get out there and go about the process of creating and making more wonderful music to share with the world. It takes all kinds of music to keep this world turning and there is someone out there that is waiting to hear the music that you create. The process of how to copyright music is completely free. The process of registering your copyright is worth every penny you will spend. It is important to protect your music now more than ever with piracy and widespread downloading providing significant reductions in profits for everyone involved. The music industry is also a very fickle industry and you need to maximize your profit potential and usefulness. Once you understand how to copyright music, you need to make sure every piece of music you have has been copyrighted, then you need to go through your music and systematically register each and every piece as well. Even if you must do one piece at a time until you manage to register the copyright on them all, it is much better to be safe than sorry should you ever go to trial in a copyright infringement case. Also remember to pay it forward and support up and coming musicians by sharing the information of how to copyright music and how to register copyrights as well.
The Top Virtually Bug-free Free Email Services on the Net Virtually bug-free e-mail services are available actually from several places. Many of these service providers are big names, known by many, especially Internet users. The difference between the different e-mail providers lies in several things. These differences include but are not limited to plenty storage space, effective spam filtering, a fast user-friendly interface, desktop e-mail program access and much more. Currently in the United States and the rest of the world, the best offer for free e-mail comes from Gmail. Gmail is part of the Google business enterprise (the search engine most of us know) and offers the most features and storage space for their users for free. With virtually unlimited storage capacity for e-mails, a user never has to delete any e-mails of the server and can collect all the messages. Gmail offers a simple user-friendly interface, which also includes an excellent search function that lets a user find messages instantly and precisely. Another great feature of gmail is the POP and IMAP access features. This gives the user the possibility to download the e-mail from the server with any e-mail program that the user generally would use. The program can then also automatically download the e-mails into the program ready for the user to read. Gmail is funded by displaying advertising next to the e-mails read. Next on the worldwide list would be GMX, a German provider that offers many of the features gmail offers, but with limited storage space. This program also has the POP feature and can therefore be used in conjunction with any of the common available PC e-mail programs. Right after gmail it is one of the most reliable e-mail services, but unfortunately they discontinued the English user face and only offer a German version now. Thereafter on the top free e-mail services providers is AIM Mail. It is the free web-based service from AOL. Like gmail it offers virtually unlimited online storage, excellent spam protection and a simple, easy to use interface. Unfortunately, AIM Mail lacks proper productivity, such things as labels, smart folders and message threading is not available. AIM Mail also offers a very functional POP and IMAP access. Yahoo! Mail would be the next e-mail service that should be mentioned on the list of the top virtually bug-free services on the Internet. Yahoo also offers virtually unlimited storage space for e-mails and a few other nice features, such as Short message services for texting to friends and family, instant-messaging features for the internet and up to date news feeds. What Yahoo! mail lacks is a really good spam filter. It offers a spam filter, but it is not effective enough. Also nice to have would be labeling options as well as smart folders. The Yahoo! Interface is just as easy and user-friendly as the other providers and fairly reliable. To complete the list we need to mention the following three services, Inbox.com, FastMail and Hotmail. Inbox.com offers e-mail users 5 GB of free space to store e-mail online. Despite the limited space, this service is outstanding due to its high-speed accessibility. Web access and POP access are very fast and even the search functions are faster than with most other services on the market. The drawbacks of Inbox.com are the missing IMAP access, only POP is provided and the organizing of mail is slightly unorganized due to missing smartfolder technology. FastMail on the other hand offers users only IMAP. It has many useful features and has one of the best web-based e-mail interfaces. It also generally displays fewer ads then the other services do. And lastly, Live Hotmail should be mentioned here, since most PC users that have a Windows based operating system will have heard of hotmail. This program offers 5 GB of storage for e-mails online. It has a fast search option, a solid security feature and the interface is as easy as the ones users are used to on their desktop. Even though security is great, the spam filter is not quite as effective as some of the other e-mail providers. Also missing with this provider is the POP and IMAP access as well as smartfolders and other great e-mail organizing features.
