way to clean up db files

[gopher2 at sdf.lonestar.org]

  my db files i have 30 lines like this

vpn_client1             A               192.168.5.225
vpn_client2             A               192.168.5.226
vpn_client3             A               192.168.5.227
vpn_client4             A               192.168.5.228
......
vpn_client30             A               192.168.5.254

also my reverse lookup is the same

225                     PTR     vpnclient1.example.org.
226                     PTR     vpnclient2.example.org.
227                     PTR     vpnclient3.example.org.
....
254                     PTR     vpnclient30.example.org.


is there any way i can do this on just one line
i think i seen it before but not sure
