CARP uses the same MAC address range as VRRP. From the VRRP RFC:
7.3 Virtual Router MAC Address
The virtual router MAC address associated with a virtual router is an
IEEE 802 MAC Address in the following format:
00-00-5E-00-01-{VRID} (in hex in internet standard bit-order)
The first three octets are derived from the IANA's OUI. The next two
octets (00-01) indicate the address block assigned to the VRRP
protocol. {VRID} is the VRRP Virtual Router Identifier. This
mapping provides for up to 255 VRRP routers on a network.
Since IANA comes from DARPA, it's not particularly surprising that the
manufacturer would be listed as the U.S. Department of Defense. However,
the relationship between DARPA and IANA is less direct now and the
influence of large corporations is increasing - it's probably more
technically accurate to list "The Military-Industrial Complex" as the
manufacturer.
