They all drive on the same TCP/IP highway, just for different purposes.
If you want the IP address of a domain name such as meebo.com, go to a command prompt and type NSLOOKUP and hit enter.
Then type the domain name and hit enter.
The Name Server Lookup will return the IP address of the domain name or host name that you have requested.
If you want to know what the mail server(s) name(s) for that domain are, then at the NSLOOKUP prompt, change the lookup type from A records to MX records (mail exchanger) by typing the following:
SET TYPE=MX and enter
Then type the domain name again and hit enter. You will then get a list of the MX records assigned to that domain. You can then return to the A record lookup by typing
SET TYPE=A and enter
Then type in the host names for the mail servers and it will return the IP address.
Type EXIT and hit enter to return to the normal command prompt.
