Which altavista.com site are you looking at? I can't see anything like this

when I view www.altavista.com.



That said, IP addresses are *not* distributed by geographical region

(country or otherwise). I know of only two ways where you can get an the

location of the IP address, and even then it's not gaurenteed to be

accurate:

a) You can do a reverse DNS lookup on the IP and see if it has a DNS name,

eg if you do a reverse lookup on my IP address, you will see it resolves to

test.careers.unsw.edu.au, which would lead you to assume that I'm in

Australia - actually it merely means that my IP has an entry in the DNS

underneath the .au domain, but 90% of the time they should correspond.

b) Look up the owner of the netblock by querying one of the registries that

hands out IP addresses. Again, this is not accurate, just because the Uni of

New South Wales, Australia, has the netblock 129.94.xxx.xxx does not mean

that I'm in Australia physically.



Cheers

Hi,

You can use some third party components like ASPDNS from ServerObject to 

resolve the IP to DNS.You have to figure out the later part wherin you can 

relate the DNS names to the countries.



I think you gotto build this DNS database & the related countries.



Regds,

Harsh
