TCP Port 53001

About TCP Port 53001

Port 53001 has no formal IANA registration. This port falls within the dynamic/private port range, which IANA explicitly does not register; these ports are intended for ephemeral or temporary use. It does not currently appear in the IDS rulesets or malware activity indicators in our data sources. Unregistered ports are still commonly repurposed by local software, games, and occasionally malware, so verify what is listening before allowing traffic.
