Checking six of our name servers here (some pure recursive, some pure authoritative): - 11,125,766,153 IP packets received, with 0 bad header checksums - 9,311,954,730 UDP datagrams received, with 1,300,228 bad checksums Thus IP header checksum really looks like it is very close to zero, probably because any IP packets with bad header checksums would be dropped by the closest router. However, the UDP bad checksum rate is very definitely not zero. I get a rate of 1.39e-4 for my dataset.
