Networking 101

IP addresses

Every machine on the internet has an ip address. Far too often users in IRC ask "Whats the ip of" Every domain name (that's in use) resolves to an IP address. Domain names are only aliases for IP addresses because is easier to remember than The inverse is not neccesarily true--an ip may have no domain name. Also note that several different sites under different domains may share an IP.

Finding IPs

The ShowIP Firefox extension displays a site's IP address in the Firefox statusbar, and the extension works on Windows and Linux. Read: If you aren't a macfag, just use it. * nix, OS X januszeal@sumomo ~ $ host is an alias for has address has address has address has address or chance@AMD64:~$ dig

<<>> DiG 9.5.0-P2 <<>> IN A 42327 IN CNAME 94 IN A 94 IN A 94 IN A 94 IN A
* Windows C:\Documents and Settings\janus zeal>ping Pinging [] with 32 bytes of data: Reply from bytes=32 time=40ms TTL=50 Reply from bytes=32 time=44ms TTL=50 Reply from bytes=32 time=38ms TTL=50 PINGING A HOST WILL NOT CAUSE ANY KIND OF HARM TO IT, STOP TRYING TO TAKE DOWN SITES BY PINGING THEM YOU FUCKING RETARDS. Hmm... The FireFox extension FoxyFlag may be interesting. It supposedly gives you a site's IP, although when I did on google it gave me * That is correct, however I find Domain Details to be a better add-on janus zealtalkwat 01:54, 8 July 2008 (UTC)

Web hosting

Every site is being hosted on someone's server. Finding out which company hosts a site is a good way to find out what kind of bandwidth packages they have, etc.

Finding domain name registrar

   * go here [<>](
   * Enter the domain name
   * look for Registrar 

*nix based systems

On all *nix based systems it's pretty easy to find out any available details about a domain. That's what the command 'whois' is for. Every domain registrar runs a whois database for the domains it is hosting. Their database usually contains information about the owner of the domain, a technical and an administrative contact including addresses of them (admins doing semi-legal/illegal things may lie on these forms). Some registrars require that the administrative contact is a natural person, not an organization. Some domain owners subscribe to privacy services (such as Domains by Proxy) in which case you will have to try another way to get the information. Usage example: $ whois

Finding host

Once you have an IP address, you can find out who is hosting a site. * go here * enter IP address * look for OrgName * ??? * PROFIT!
