Technical Details

what runs on :654

AODV is defined by RFC 3561 and normally sends routing messages over UDP port 654; although the registry lists both TCP and UDP, TCP is not used for normal AODV operation. Route Requests (RREQ), Route Replies (RREP), Route Errors (RERR), and optional HELLO messages support on-demand discovery and maintenance of hop-by-hop routes. AODV has no conventional connection handshake or encryption layer, and its messages use protocol-defined binary fields rather than an application stream framing protocol.

security overview

AODV assumes a trusted or otherwise protected ad hoc routing environment. An exposed implementation can be targeted with forged route messages, route disruption, blackhole or sinkhole behavior, and resource-exhaustion traffic; it should generally be restricted to the intended ad hoc or mesh interfaces and never exposed broadly to the public Internet.

Record

port: :654
service: Ad hoc On-Demand Distance Vector (AODV)
transport: TCPUDP
encryption: cleartext
assignment: iana registered
risk: 2/10safe
category: Network Services System
usage: AODV is a reactive routing protocol for mobile ad hoc and mesh networks, typically using UDP port 654. Engineers encounter it in implementations of wireless ad hoc routing rather than in ordinary Internet-facing hosts.
