Fragment Header for IPv6 - IP Protocol

This page provides IP protocol information on the Fragment Header for IPv6 IP protocol (IPv6-Frag) detected by the Netify DPI engine. Please see the IP protocol catalog for information on other IP protocols.

IPv6-Frag is the IPv6 Fragment extension header, used by a sending host to fragment a packet that is too large to fit within the path's maximum transmission unit. Linux has a native handler for this IP protocol.

IP Protocol Status - Active

IPv6-Frag has been part of the core IPv6 specification since the 1990s (now RFC 8200), and remains an active, standard part of IPv6 fragmentation handling.

IP Protocol Network Policy

IPv6-Frag is required only where IPv6 packets must be fragmented in transit or by the sender; many networks restrict it since fragmentation is a known evasion and DoS vector.
