ICMP for IPv6 - IP Protocol
This page provides IP protocol information on the ICMP for IPv6 IP protocol (IPv6-ICMP) detected by the Netify DPI engine. Please see the IP protocol catalog for information on other IP protocols.
IPv6-ICMP is ICMPv6, the IPv6 counterpart to ICMP, used for error reporting, diagnostics, and essential functions like Neighbor Discovery and address autoconfiguration. Linux has a native handler for this IP protocol.

IPv6-ICMP is required for core IPv6 functions including Neighbor Discovery, address autoconfiguration, and path MTU discovery; blocking it breaks IPv6 connectivity entirely.
