question about DHCPACK log entries

I have a script that parses our dhcp logs to generate a happy little table
of mac->ip addresses mappings for a particular subnet. Because I only
care about the one subnet, I was doing a regular expression match on the
gateway IP. But then I noticed that the format of the DHCPACK log entries
isn't always the same - and sometimes doesn't include the gateway address.
Examples follow. Can someone shed a little light on what is happening
here? We are running 3.0.4, fyi.
Log entries in question:
Mar 1 12:45:48 ns1 dhcpd: DHCPACK on 128.193.143.180 to 00:16:6f:67:89:e6
via 128.193.136.1
Mar 1 12:45:48 ns2 dhcpd: DHCPACK on 128.193.143.180 to 00:16:6f:67:89:e6
via 128.193.136.1
Mar 1 13:11:02 ns1 dhcpd: DHCPACK on 128.193.143.180 to 00:16:6f:67:89:e6
via eth0
Mar 1 13:11:11 ns1 dhcpd: DHCPACK on 128.193.143.180 to 00:16:6f:67:89:e6
via eth0
Notice that at 12:45, the ACK log entry includes the gateway address, but
at 13:11, it does not. Why is that?
Thanks in advance.
