So that applications on your system can perform a remote ident request. I
don't know of any program that requires ident to work. Some (like ssh in
some configurations) will try it to get more information about the remote
user by trying an ident call over the network.

$ grep 113 /etc/services
auth            113/tcp    ident tap    #Authentication Service
auth            113/udp    ident tap    #Authentication Service

You may also try sockstat, netstat, and tcpdump.
