SLP v1 vs v2

So I have two SLES 11.2 OES 11.1 servers. One located in a different office and one local to me. Both are running as SLP DA's. I rebooted my XP machine to see if it found them both via DHCP, which it did.. but the remote one says SLP v1 and local one says SLP v2 via "slpinfo /all"

Not sure what to make of that..
