The TTL (Time To Live) field in the IP header has a double significance in multicast. As always, it controls the live time of the datagram to avoid it being looped forever due to routing errors. Routers decrement the TTL of every datagram as it traverses from one network to another and when its value reaches 0 the packet is dropped.

WebWhat is the IPv4 header’s maximum TTL count? TTL is an 8-bit field in the Internet Protocol. TTL is the 9th octet of 20 in the IPv4 header. It’s the 8th octet of 40 in the IPv6 header.
