Technical Details

what runs on :435

IANA lists both TCP and UDP, but Mobile IPv4 control traffic is normally carried over UDP rather than TCP. A mobile node uses the registered endpoint for binary Mobile IP registration messages and replies, consisting of protocol headers followed by authentication and other extensions; it is not a general-purpose application session. Mobile IP agent traffic is conventionally associated with UDP port 434, so an open TCP/435 listener is unusual and may represent a vendor-specific or unrelated service.

security overview

Mobile IP signaling is not encrypted by default. Registration messages should be protected with the protocol's authentication extensions and should generally be permitted only between known mobile nodes and home or foreign agents; exposing the port broadly can allow spoofed registration attempts, denial of service, or routing-related abuse. Because the protocol is rarely deployed, unexpected listeners on this port should be identified before being treated as Mobile IP.
