  "whatItIs": "IANA holds 425 as icad-el, described only as \"ICAD\" and assigned to an individual registrant. No protocol document, vendor page, or open implementation for it survives, so the registration is the entire public record. The port has a negligible open rate in Nmap's frequency data. If you find something listening on 425, the registered name is not evidence of what it is — probe the service and check the process on the host.",
