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.
Events of copyright infringement The Events of Copyright Infringement: Innocent People Infringing Accidentally Copyright infringement is in the news a lot lately – it’s hard to miss stories about kids being carted off to jail or seriously fined for downloading music or movies off the internet. I’ve even heard about a lady was fined for tens of thousands of dollars because of the events of copyright infringement – her grandson downloading music, and she couldn’t prove it wasn’t her. The events of copyright infringement are complicated – and not easy to define. Surfing the internet has its advantages and disadvantages, that’s for sure. We’re able to find useful information quickly, but how close are we pertaining to copyright laws? Do we even know what is and is not acceptable? A couple of the more pertinent questions have been asked below: If you hear a great new band, and then download a song from MySpace, is that legal or not? The events of copyright infringement are not only limited by Kazaa, Morpheus, or some other file sharing peer to peer (P2P) service. If you download a song - no matter if you’re on a website or a MySpace page - and it isn’t coming from the artist themselves, you may want to think about downloading it. Chances are, if it’s not coming from them, you can’t have it – unless it is under a Creative Commons License. Creative Commons gives the exact ways in which you can use the license – and many times those are completely free and legal to download – so make sure you check if it’s under a CC License. If I’m writing a paper, or article, and I want to quote another website, can I? First of all, did you know the minute you write or create something, you hold the copyright to it? ESPECIALLY if you’re writing it online – it’s very easy to track things in the internet page. So, if you’re writing a blog, all the things you’ve written (no matter good or bad) are there permanently, thanks to archive.org, and you can review last versions of your web pages. Sometimes, people we can use – rather heavily – someone else’s work in our own, and think we’re small and anonymous. That no one will notice by the time you get it down – you’re just ‘borrowing’ it. Before you begin quoting anyone’s website – from CNN to your local neighborhood hardware store – you need to ask the person who holds the copyright if you can. Usually, they’ll let you if you attribute to them. Depending who you talk to, you’ll either have to pay royalties or license rights to republish. If you don’t ask before you quote, you’re beginning the events of copyright infringement and you are opening yourself up for a lawsuit. As you can see, the events of copyright infringement can begin at any time, beginning with normal ‘everyday’ activities. It’s just as easy to infringe on as it is to be infringed upon. Make sure you check your copyright using CopyScape or some other service, and you can check your work against other works on the internet, and make sure that you’re not infringing someone or vice versa. In this day it’s easy to protect yourself from getting infringed upon, and the events of copyright infringement are easy to track. It’s easy for innocent people to get caught in copyright infringement, like children they didn’t know what they could and couldn’t do. Make sure, in all you do, that you’re striving to do the best you can, and you’ll be certain not to fall victim to your own infringing demons. Everywhere You Look There are Creative Writing Prompts (creative writing prompts) As glamorous as creative writing prompt sounds, it is nothing more than they start of an idea for your writings. A prompt could be virtually anything from a picture to a dream, whatever gives you that “Oh that would be a great story” feeling is your prompt. Like a movie preview it gives you a taste of what is to come or a sample at a store that makes you want to buy the product. It could be a single word or a collaboration of words. Whatever it takes to get the story into your head and then onto the paper would be considered a creative writing prompt. The need of finding creative writing prompts often stems from having writers block. If coming up with your own prompts has become difficult don’t worry. There a literally millions of prompts out there. You just need to find the right ones for you. Take the Internet for example. Do a search for creative writing prompts. You now have pages and pages of story starter’s right at your fingertips. You have many options available while searching for prompts. From one or two words starters to a brief synopsis of an idea they are available to you. Some sites offer daily prompts. They will even email them to you. There are many books available with nothing but lists of prompts just waiting to be turned into great stories from your mind. There are a lot of writers that feel that using lists of prewritten prompts by someone else is cheating. They feel that all prompts used must be their own. But truth be told, there is not a creative writing prompt that has not been wrote about. It is the creation that comes after the prompt that makes the writing your own. The prompt is not what your creative writing is all about, but a springboard for your imagination. It is merely what opens the portal to your imagination, to your passion, and to your thoughts. Sitting at your computer and staring at the blank page will most likely give you a headache before a great idea. Go outside, close you eyes, and clear your mind. Listen to the sounds around you. What do you hear? Children’s laughter, neighbors chatting, or ever the birds chirping. Let those sounds drift away and your mind float. Slowly letting things come back into your mind, your last trip to the beach, your kids at the playground, your spouse cooking dinner any of these can be an idea jogger that gets the creative writing flowing. These thoughts alone could spark a hundred ideas just waiting to be words on your canvas. It also may help to keep a notebook with you at all times. That way whenever you have a great idea you can jot it down before it escapes you. Many writers only use creative writing prompts from outside sources. They are given to them by editors and publishers telling the writer what they want you to write about. Some writers work better this way being given the idea and running with it. Others prefer using their own. Creative writing prompts not only help initiate ideas, they also help spark your memory for you to write about your own past experiences and adventures. You can use them for writings on your website or blog. Whether you use outside sources for your inspiration or use your own it does not affect the integrity of the words that complete the idea. The story behind the prompt is the vision of your creative abilities, not the prompt itself. |
