As I stated above, DNS is normally a translation service from pc readable names, to human readable names. The theory is comparable to a telephone book, or directory assistance, which translate telephone numbers to names. The DNS system is distributed across the complete Internet, virtually each and every Internet provider has two or more DNS servers, most hosting companies do as well, and a good deal of substantial businesses, ie Microsoft, Dell, HP all have their personal servers. (of course, having 30,000+ employees, they almost certainly have their personal directory assistance too).

Every single particular person on the Web uses DNS, 99% of them with out even knowing. Every time you go to a website, you do a search of the DNS method to discover the place of the site. Every time you send an email, your ISP’s mail server does a DNS search to find the mail server for that domain. There are actually a lucky 13 master servers, that include a list of which DNS servers deal with which domains, when you appear for a domain that your ISP’s DNS server doesn’t know, it asks the master servers, which DNS server does know about this domain, then it asks that DNS server for the details it needs, prior to passing it back to you.

Changing DNS Servers

When you alter hosting providers, the standard procedure is to also change your domain’s delegation towards the new hosting providers DNS servers. This procedure, known as redelegation, is best, as it indicates one business handles every thing for you, and if they make a change to the place of one’s website, for example moving it onto a quicker server, they also can update the DNS records straight away, so no one notices. To discover out who your domain is delegated to, you need to have to complete a ”whois search”. A whois search won’t show you where your web page is, however it will show you which DNS servers know where it is. Customers of Anchor must always see ”’ns1.anchor.net.au”’ and ”’ns2.anchor.net.au”’ in their whois information. If your domain is currently with an additional company, and you will need to bring it to Anchor, you require to alter that information. Generally, this is done by way of a web page of the provider that you registered the domain with, it is really a straightforward change.

Buzzwords & Geek words, translated!

Often when talking about DNS, the words (and abbreviations), ”’TTL”’, ”’Cache”’ and ”’Propagation”’ come up, but what do they mean? In plain English, the DNS server responsible for your domain has a file with all of the details about your domain in it, and when one more DNS wants details about your domain it’s pulled from this file, together with a TTL value. TTL stands for ”’Time To Live”’, and it may be the maximum time a foreign DNS server can store this information locally, devoid of asking if it has changed (the approach recognized as caching). When you redelegate your domain from 1 DNS server to another, the quantity of time it takes depends upon the TTL value within the old server.

As I said above, there is often a solution to speed up the process, and that is to redelegate a week early together with your new hosting business copying the old records, with a very low TTL, (ten minutes or so), after which when you are ready for the internet site and email to go to the new server, altering them on the new DNS server. This implies the complete Internet will see the change in 10 minutes, regardless of the domain name (note, some ISP’s usually do not confirm towards the normal for DNS caching, and could not update instantly).

So what does a domain record appear like

@ IN SOA ns1.anchor.net.au. hostmaster.anchor.net.au. (
2004030401 ; Serial
28800 ; Refresh
14400 ; Retry
3600000 ; Expire
86400 ) ; Minimum
@ IN NS ns1.anchor.net.au.
IN NS ns2.anchor.net.au.
IN MX 50 smtp1.anchor.net.au.

IN A 202.4.234.122
smtp IN A 203.98.94.10
www IN CNAME @
ftp IN CNAME @
mail IN CNAME smtp
pop IN CNAME smtp
pop3 IN CNAME smtp

That looks scary! What does it all mean?

Lets breakdown the file one line at a time

@ IN SOA ns1.anchor.net.au. (

86400 ) ; Minimum

The worth of minimum is the TTL, ie the length of time, other servers can cache the information for the domain

@ IN NS ns1.anchor.net.au.
