on linux, if you have a nameserver configured and if the name server knows the target host's ip ( that is, if the target host is listed in the nameserver records, called A records), it will return the ip address.

All important systems do have the A record on the nameserver.

You can use dynamic dns updates with dhcp to ensure that the hostname of each host that gets a dhcp address is promptly updated in the dns database.

into a console type : ping computername

my output:

' root@egag12:/# ping xs4all.nl
PING xs4all.nl (194.109.21.2) 56(84) bytes of data. '

( it keeps pinging , i use ctrl-c to exit )

...or to find all IP's associated with the hostname, use the host utility...

Code:

hw@royne:~$ host xs4all.nl
xs4all.nl has address 194.109.21.2
xs4all.nl has address 194.109.21.3
