All the recent discussion about mDNS caused me to fire up Wireshark, to look at some mDNS packets. I have seen several queries and responses. The queries have a TTL of 1, which is per spec, but the responses have 255. Why is this? Multicast addresses in the 224.0.0.0/24 range are supposed to only have a TTL of 1. The IPv4 address for mDNS is 224.0.0.251. Typical TTL for outgoing packets is 64. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
