This data is collected by sending UDP datagrams to random IP multicast groups which elicits replies from broken routers. RFC1112 section 7.2, RFC1122 section 3.2.2 and RFC1812 section 4.3.2.7 all prohibit sending ICMP errors in response to multicast. See the consequences and a brief history of this problem.
Note that the SNMP Info may be newer than the last time we received an ICMP; this is a limitation of our measurement technique.
