Technical Details

what runs on :8611

BJNP is a proprietary, typically cleartext Canon device protocol available over TCP and UDP. Hosts use it for printer status, job submission, and related device operations; TCP port 8611 is the primary BJNP printing endpoint, while port 8612 is commonly associated with a second BJNP function such as scanning. It is not a standardized or encrypted application protocol, and exact message framing and supported operations vary by Canon model and firmware.

3/ 10caution

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

system averages 2.7 across 714 ports — this one sits 0.3 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

BJNP should normally be restricted to the local network or a printer VLAN, not exposed to the public internet. Devices may accept status queries or print-related operations without strong authentication, and traffic can disclose device information or job data; use firewall rules and network segmentation to limit access.
