Technical Details

what runs on :8612

Canon BJNP is a proprietary, generally unencrypted protocol carried over both TCP and UDP. Compatible Canon devices listen on port 8612 for BJNP Port 2 traffic; port 8611 is the related BJNP Port 1 service. Hosts such as Canon's printer/scanner utilities and platform drivers use these ports for device communication and job or scan operations. Exact message formats and handshake behavior vary by device generation and are not publicly standardized.

4/ 10caution

worth attention. how exposed you are depends on configuration — don't leave it reachable from the internet without a reason.

network services averages 2.7 across 1,375 ports — this one sits 1.3 above.

assignment

official

registered with iana for this service — scanners fingerprint it by number

tcp · udp

udp is connectionless — source addresses are trivially spoofed and it is a reflection favourite

security overview

This is intended for trusted local networks, not direct Internet exposure. Because BJNP traffic is normally cleartext and device authentication is limited or model-dependent, an exposed service may disclose device information or permit interaction with printer/scanner functions; restrict it with network segmentation and firewall rules.
