The easisest method is to retrieve the hostname from the output of the
'who am i' command. After doing this, I simply arp the name to get the
IP address.
Suggestions were made to use the utmpx database and retrieve info via
getutxent(), but the trouble of making this work lost out to the ease and
quickness of the above solution.
