This page provides IP protocol information on the Inter-Domain Routing Protocol (IDRP) detected by the Netify DPI engine. Please see the IP protocol catalog for information on other IP protocols.
IDRP is the Inter-Domain Routing Protocol, an OSI-based protocol designed to exchange routing information between separately administered networks.

IDRP was standardized by ISO in the early 1990s as an OSI counterpart to BGP, and is obsolete, as OSI routing was never widely adopted.
IP Protocol Network Policy
IP protocol #45 - Inter-Domain Routing Protocol - is typically dropped by edge routers and firewalls. Advanced threat actors and malware families can use these non-standard IP protocol numbers for lateral movement (east-west communication) inside internal networks.
