WebMinimum required field size of IPv4 header is 20 bytes. Minimum required length of an IPv4 header is five 32-bit words (5*32 = 160 bits or 20 bytes). The length of required fields in IPv4 header is 20 bytes. Maximum possible is fifteen 32-bit words (15*32 = 480 bits or 60 bytes). WebWhen an IPv4 node performs path MTU discovery (by setting the Don't Fragment (DF) bit in the header), path MTU discovery can operate end- to-end, i.e., across the translator. In this case, either IPv4 or IPv6 routers (including the translator) might send back ICMP Packet Too Big messages to the sender.
