Chapter 30

30.1	Use Whois to find the owner of the class A network ID 88.
A:	Type `whois "net 88".` Class A network IDs 64 through 95 are reserved.
30.2	Use Whois to find the DNS servers for the `whitehouse.gov` domain. Does the reply match the answer given by the DNS?
A:	Type `whois whitehouse-dom.` Either the `host` command or `nslookup` can query the DNS.
30.3	In Figure 30.3, do you think the `xscope` process must be run on the same host as the X server?
A:	No, `xscope` can run on a different host from the server. If the hosts are different, then `xscope` can also use TCP port 6000 for its incoming connection.
