WIP_NET_OPT_IP_TTL Default TTL of outgoing data grams
This option is a limit on the period of time or number of iterations or
transmissions that a unit of data can experience before it should be discarded.
The time to live (TTL) is an 8-bit field in the Internet Protocol (IP) header. It is
the 9th octet of 20. The default value of this parameter is 64. Its value can be
considered as an upper bound on the time that an IP datagram can exist in an
internet system. The TTL field is set by the sender of the datagram, and reduced
by every host on route to its destination. If the TTL field reaches zero before the
datagram arrives at its destination, then the datagram is discarded. This is used
to avoid a situation in which an undelivered datagram keeps circulating in the
network.
