The obvious two ways to carry the ILNP Identifier with ILNPv4 are either as an IPv4 Option or as an IPv6-style Extension Header placed after the IPv4 header and before the upper-layer protocol (e.g., OSPF, TCP, UDP, SCTP). Currently deployed IPv4 routers from multiple router vendors use An IP packet consists of a header section and a data section. An IP packet has no data checksum or any other footer after the data section. Typically the link layer encapsulates IP packets in frames with a CRC footer that detects most errors, many transport-layer protocols carried by IP also have their own error checking.
