Hostname differences between servers

[Norman Elton]

In our environment, we have multiple routers (VRRP) forwarding
requests to two DHCP servers, run in failover. So if a client
broadcasts out a DHCPREQUEST, that message is handled multiple times.
Not a big deal, it's been working great for years.

We've just noticed that, sometimes, the hostname reported by the two
servers don't match each other. For instance:

Oct  1 01:03:48 landlord01: DHCPREQUEST for 10.45.13.196
(128.239.10.121) from e8802ea2eb7f (Michaels-iPhone) via 10.45.13.2
Oct  1 01:03:48 landlord02: DHCPREQUEST for 10.45.13.196
(128.239.10.121) from e8802ea2eb7f (android-9375f90cad51e32f) via
10.45.13.2: lease owned by peer

So, is it an android, or is it an iPhone? In this case, the mac
address points to Apple, but why is one server reporting the hostname
is android-9375f90cad51e32f?

This is happening fairly frequently. Our servers are running the
RHEL-provided version of ISC dhcpd, 4.1.1-61.P1.el6_10.

Any ideas?

Thanks,

Norman
