  "oneLiner": "Unassigned; IANA registers nothing between 14414 and 14500, and 14441 sits in that hole.",
  "whatItIs": "IANA leaves 14441 unassigned — the surrounding registrations are `ca-web-update` (14414, CA eTrust Web Update Service) and `xpra` (14500, the xpra network protocol). Nmap's service table lists it as `unknown`. No published product default, malware family, or scanner signature is tied to it. Note that 14441 and 14442 are frequently seen together, which usually means one application claimed a small consecutive block for a control and a data channel rather than that either number is registered.",
