[AusNOG] Incorrect DNS setup

It isn't so much as 'incorrect' as convention and arbitrary.

'www' serves no purpose whatsoever...  and I am actually quite happy when i see a '<domain>.com.au' on a bus or advert with no 'www'.

That said, we've been using www for sooo long that it would be stupid of people not to have an A record for it as well.

You will probably find that www1, www2, etc are probably load balanced environments.... or dedicated websites for sub-content with the primary www handing off to either geographic or resource based servers (or both).

In the end it is about personal choice... but to use one and ignore the other, is a bit stupid in my opinion.

Hey Noggers,

Firstly I would like to apologise for going a-wall postal on you all yesterday... and a big thanks to those who off list posted me to discuss last mile setups and what not, and generally giving me a helping knowledgeable hand :)

So heres my post for today:

Very frequently I trawl around and go to peoples websites (especially when I see an email on ausnog with a domain I haven't been to attached to it ;P )

I have done this again this morning and it got me thinking, how come a lot of people have these two cases:

A) I navigate to blah.com.au<http://blah.com.au> and is goes "can't connect to this server" I append www. to the domain (it ends up being www.blah.com.au<http://www.blah.com.au>) and I get their website.

or

B)The reverse of this, I navigate to www.blah.com.au<http://www.blah.com.au> and it says "Can't connect to server", but I go to blah.com.au<http://blah.com.au> and it is all cool.

What I am wondering is:

A) Why do people leave have these cases?

B) Where did the use of appending www. to the front of things originate from?

C) also I see sometimes www1. or www2. on some websites, can someone explain these to me?


Thanks guys,
Hope your all having a nice monday morning.

Cheers!
Karl Kloppenborg
