How to lookup an IP address...

[r0g]

Not the visitors IP address, or rdns, indeed they seem to be getting in
the way of my googling for the answer despite qualifying my searches
with -reverse and -remote_addr

No, what I need is a good old fashioned DNS lookup.

e.g. $ip = dns('www.poo.co m');

I know I could just pop a datagram off to port 53 and parse the result
but I feel sure php must provide a built-in for this fairly fundamental
task and that I'm just being lame at finding it.

Thanks,

Roger.

Maybe dns_get_record( )?

Thanks Jerry,

It turns out dns_get_record is kind of overkill for what I need though.
It returns the domains entire DNS record and it doesn't work on Windows,
Mac , BSD or PHP4 however - it did lead me to stumble upon the function
gethostbyname() which does exactly what I am after :0) so thanks v.much!

Surprise surprise it turns out that's what they call it in C too! Doh!
