The nslookup command allows you to match a machine's Internet domain name
(such email1.cc.uic.edu) with its IP address (such as 128.248.150.51) or vice
versa. There's a nslookup command tigger and icarus. It's in WS Ping
Tools in the Windows Network Services Kit (or you can open a DOS window and
enter the nslookup command directly). There are also various nslookup Web sites,
including InfoBear's http://www.infobear.com/nslookup.shtml.
Most nslookup utilities determine the search type from the format of
the input. I logged into tigger to run these nslookup commands:
>nslookup email1.cc.uic.edu
Server: uic-dns2.uic.edu
Address: 128.248.7.50
Name: email1.cc.uic.edu
Address: 128.248.150.51
>nslookup 128.248.150.51
Server: uic-dns2.uic.edu
Address: 128.248.7.50
Name: email1.cc.uic.edu
Address: 128.248.150.51
(Wondering what the email1.cc.uic.edu here and in figure
2 is? My email account is on mailserv, which, at this time, is a cluster
of two Unix machines. My account happens to be on the second of the two machines,
email1. The first is email0.) |
