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.

Family Entertainment – How to Get a Free Ticket for your Child Free tickets are not something that can be found very often, but every once in a while there is a company that offers a free ticket for your child. How about a free ticket to the circus? Almost all children love the circus and there will be that point in time when a child sees the circus come to town and wants nothing more than to go to one of the shows. Honestly, circus visits can break the monthly budget that was planned so carefully, not taking in account such activities. Well, the circus actually offers a free ticket to children of all ages, as long as that ticket has been requested within baby’s first year. On his or her own web page, the circus offers the ticket to anybody that signs up for it. As babies grow, many new things come along, baby will learn to crawl, baby will get the first teeth and at some point baby will be big enough to visit the circus. The First Circus program is for parents and their newborn up to twelve months that are living in the Unites States. All the parents have to do is to visit the circus own homepage and sign up for the program, to receive a free ticket voucher and a special personalized baby certificate. The certificate is printable online and the ticket voucher will be sent to the parent’s home address. The voucher can be exchanged for a free ticket to any of the participating circus performances, anytime, anywhere. The voucher does not have an expiration date. Unfortunately for parents that did not know about the program and whose children are older than twelve months there is only the possibility to receive a commemorative certificate and no free ticket. Therefore it is important for all parents to find out about this wonderful program that will help their child to their first circus experience without breaking the parent’s bank account. On the other hand, the circus visit is free for children under the age of two as long as they sit on an adults lap. By the way, if a child was adopted after the age of twelve months there is still a chance for a free ticket as long as the parent requests it as per direction on web page within the twelve months after adoption. In general the circus will only give a way one free voucher per family per year, but they will make exceptions for parents of multiples. Parents of multiples will have to check out the circus page and follow the directions given there. Since it is not possible to order more than one free voucher besides the few exceptions, every duplicate order that is done by parents after signing up for the first time will delay the original order for the free voucher. It might be also important to know that this free ticket is a very good deal, since children’s tickets have the same price as adult tickets for circus performances. Sometimes, in bigger cities there are special offers from bigger supermarket chains or other places, where a discount on tickets is given, but in general the circus itself does not offer any other discounts. Any parent should take advantage of this First Circus program, since it is not often that companies do give away tickets for free. Circus also has never lost its magical and still pulls the crowds and makes children gasp in astonishment or laugh out loud when seeing the circus clowns. How often do children nowadays have a chance to see elephants stand on their back feet, artists balancing on ropes or swinging and flying through the air and funny clowns fall over their own feet? |
