Technical Details

what runs on :5436

UDP port 5436 is assigned to Proxy Mobile IPv6 control. PMIPv6 lets the network manage mobility without requiring the mobile node itself to perform Mobile IPv6 signaling: the Mobile Access Gateway (MAG) sends a Proxy Binding Update (PBU) to the Local Mobility Anchor (LMA), which responds with a Proxy Binding Acknowledgement (PBA). The port is intended for signaling between those network elements, not for ordinary client traffic. PMIPv6 deployments also use IPv6 mobility-header signaling, so seeing this UDP port alone does not establish that a host is running a PMIPv6 endpoint.

security overview

This control plane can affect mobility bindings and should be limited to trusted MAG/LMA peers, not exposed broadly to the internet. PMIPv6 specifications call for IPsec protection of signaling; UDP itself provides no encryption or peer authentication, so verify that the expected IPsec protection and peer restrictions are in place.

Record

assignment: iana registered
risk: 2/10safe
category: Network Services
usage: This is a specialized operator-network control service for Proxy Mobile IPv6 (PMIPv6), not a general-purpose internet service. A Mobile Access Gateway and Local Mobility Anchor use PMIPv6 signaling to manage a mobile node’s network-based mobility and binding state.
