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.
The Many Sides of Writer Web Rings (writer web rings) Generally, a web ring is defined as a collection of Web Sites from the Internet that are joined together in a circular structure. Writer web rings are a great example of this collection of Web Sites. Web rings may be used to increase search engine rankings, and can be considered as search engine optimization techniques. It is common for many web rings to take advantage of this and find writers looking to improve their own rankings. There are many web rings available for seasoned writers and novices alike. Becoming a member of one of the many writing web rings is as simple as joining any other web rings with different themes. Web ring web sites each have a common navigation bar that contains links to the previous and next sites. Clicking the next or previous sites repeatedly will eventually take the surfer to the site original site of the web ring; this is the origin of the term web ring. Web rings are organized around certain themes, and of course the theme for writer web rings is writing. These web rings for writers typically have moderators who are responsible for deciding what pages to include in the web ring. The making of the web ring is the foundation for the group of people who will soon join. Writer web rings are readily available and are open for all potential writers and experienced writers to join. These web rings for writers are usually seen as an outlet for many writers, who are otherwise unable to find interesting ways to increase their experience in the writing world.

The Accomplished Women Writers group is a group of women writers who help each other by providing tips and hints for getting published. The web ring also includes a site that teaches women how to manage a family, household, and writing career. The Aspiring Young Writers Ring is also a web ring, and is dedicated to helping young writers on their way to becoming professionals.

No matter the person, there is a writer web ring for almost every kind of writer, so no writer should feel discouraged if they feel their case is a unique one and there is no writer web ring to satisfy their artistic needs. Writer web rings are not a new concept, but there are many writers who don?t take advantage of their great services. A writer web ring can be used to help any writer expand their knowledge of writing techniques, of their own experience, level, and style of writing, can help them appreciate their writing as well as others, while teaching them about the business of writing, and helping them figure out the world of writing in general. These web rings are considered to be good things because a person can find many sites relating to their own writing all together without searching endlessly. Many may not see writer web rings as perfect, but they can be noted for their service they provide for many writers, and can be seen as a great tool for the writer.
Five Biggest Job Hunting Mistakes and How to Avoid Them Looking for a job can be a challenging experience. Between the resume writing and the interviews you can find yourself exhausted and ready to throw in the towel prematurely. Stay the course until you find the job you want. While you are on your job-hunting journey, here are five big mistakes to avoid when job hunting. Steering clear of these mistakes could make finding a job much easier. One of the biggest mistakes that people make when they are job hunting is not looking in enough places for jobs. There is a certain level of diligence you need to maintain when you are searching for a job. Look in newspapers, online and ask around. Of course, there are boundaries you should follow when looking for a job. First of all only apply and interview for jobs that you think you would take if you were offered the position. Do not apply for jobs that you are not qualified at all for or jobs that you do not have a clear understanding of. When applying for jobs, it is important to have a resume that is update and professional looking. If you are not a good resume writer, look at examples online or find a professional to do your resume for you. Employers will take one look at a messy or unprofessional resume and rule you out without ever meeting you. It is also important to be sure that you resume can be found online. There are plenty of job sites that allow users to post resumes. Some sites even allow multiple resumes to be posted. This is a great place for employers to locate your resume and contact you without you actually applying for the job. Lying on your resume can eliminate you from being a job candidate immediately. If you stretch the truth about your experience or the type of jobs you have had in the past, employers will think that you are a liar. If employers think you are a lair they will not feel confident about hiring you because you have already compromised your integrity. Tell the truth about your work and educational history. No matter what people may tell you, an honest inexperienced candidate is better than a lying experienced candidate. Have faith that you will be able to prove your worthiness for the position you are applying for without making up half-truths. Be sure that your contact information is correct and that you respond when you are contacted. No matter how busy you are, you need to check your e-mail and phone messages on a regular basis. If you do not respond to a call about a job this is a sign that you do not need employment that badly. Employers will move on to the next candidate if you are slow getting back to them. Candidates that are not prepared for their interviews are typically eliminated from the search before the interview is over. If you are late for an interview you have a big huge mark against you as soon as you walk in the door. Not being dressed in professional attire also will leave the interview with a very bad impression of you before you even speak. If you show up without a pen or copies of your resume you look like you are unfamiliar with the interview process. This, in turn, makes it quite possible that you are unfamiliar with other work place procedures. A good job hunt can land you the job of your dreams. When you are settled into your new job you will be thankful that you took the time to search for a job the right way.
