Are you recieving SMTP or other external traffic with a service that may 
be trying to resolve IP addresses to names? The IP 198.5.1.75 belongs in 
a block assigned to UUNET Technologies, Inc. but doesn't appear to have 
a reverse dns record available. It also doesn't respond to ping's. If 
you know you don't want to deal with that address, you could drop all 
packets to/from it with iptables.
