Use NSLOOKUP, specify 'TYPE=PTR', and a name of '145.50.121.128.in-addr.arpa', and you'll get the answer 'TIGGER.JVNC.NET'. Specify 'TYPE=HINFO', and a name of 'TIGGER.JVNC.NET', and you'll get the answer "CPU=Sun-4c OS=UNIX". Enter 'TELNET INTERNIC.NET', and enter 'WHOIS JVNC-DOM', to find the address of "Global Enterprise Services, Inc.", in Princeton, NJ, or enter 'WHOIS ASN-JVNC' to list some information about "John von Neumann Center".
