pings from dhcp1.cl.msu.edu

[Ben Pfaff]

I just noticed that I'm receiving periodic pings from
dhcp1.cl.msu.edu on my machine at pfaffben.user.msu.edu:

Jan  7 19:56:07 pfaffben icmplogd: ping from dhcp1.cl.msu.edu [35.8.2.22]
Jan  7 19:59:26 pfaffben icmplogd: ping from dhcp1.cl.msu.edu [35.8.2.22]
Jan  7 20:04:01 pfaffben icmplogd: ping from dhcp1.cl.msu.edu [35.8.2.22]
Jan  7 20:06:00 pfaffben icmplogd: ping from dhcp1.cl.msu.edu [35.8.2.22]

I haven't seen, or at any rate noticed, this before.  Is this
something new?  For what purpose?  (Perhaps to determine whether
DHCP leases are actually in use?)

(I would ask consult@msu.edu but they are, in my experience,
frequently wrong or simply uninformed, and slow to boot.  You
guys are generally correct and answer quickly...)
