[thelist] PHP: getting domain names from a url - being foiled by .co.uk addresses

[Williams, Olwen - SAL]

When you get to international domains in general it's going to be harder.  
.tv and .cc are really country domains, and there are many others.  (Tuvalu
and Cocos Islands).  

The registrar for the country I think determines acceptable second level
domains.
In New Zeland we have:
.co.nz .org.nz .net.nz .iwi.nz .ac.nz .cri.nz .govt.nz .school.nz .mil.nz
.geek.nz
and maybe more
Australia has .com.au .net.au etc (I don't know the lot)
Other countries may or may not use second levels

Well that would work except for the .uk.com type domains and the recent 7 
new additions.

here's some of the trickier ones:


.co.uk
.org.uk
.me.uk
.com
.net
.org
.tv
.cc
.uk.com
.uk.net
.eu.com
.gb.com
.gb.net
.biz
.info
.name
.pro
.aero
.coop
.museum

couldn't you do a DNS look up and store the IP address instead?

Maybe?
