Multiple DHCPREQUEST/DHCPACK logged for a single DHCPtransaction. Anyone seen this before?

[Steve van der Burg]

Does anyone know if this indicates that my network is messed up somehow?  Servers are a partner pair running ISC DHCPd 3.0.5.  Network is quite large, and I don't run or configure it.  I've always wondered about the two incoming gateway(?) addresses on the requests (.250 and .251).  Our official router gateways are all .254.

Is this at all normal?  These entries have been edited to remove the server name and log facility, but are otherwise posted intact:
