470
Summary
- // typical exposure
- Anomalous (rarely legitimately open) — No RFC, vendor documentation, or real-world software could be tied to this port and its measured open-frequency is negligible (~0.0013% TCP), so a responsive port 470 has no known legitimate use and should be treated as an anomaly worth investigating.
- // analyst note
- An open port 470 has no known legitimate application and negligible scan prevalence — treat as an anomaly warranting investigation rather than a normal service.
- // if you see it open
- No CVE is recorded in the NVD as of August 2026 and no credible malware/trojan association surfaced in an August 2026 search. Negligible open-frequency telemetry (~0.0013% for TCP) combined with the absence of any documented application, vendor, or protocol spec means a responsive port 470 has no known legitimate explanation; treat it as anomalous and investigate rather than assume a benign service.
About port 470/tcp.
Port 470/tcp is IANA-registered under the service name scx-proxy, but no RFC, protocol specification, or documented real-world software could be tied to it, so an open 470/tcp should be treated as anomalous and worth investigating rather than assumed to be a legitimate internet-facing service.
IANA's Service Name and Transport Protocol Port Number Registry lists 470 as dual-registered on TCP and UDP for scx-proxy, assignee Scott Narveson, with a blank Reference column — no RFC backs the assignment, and the registry itself supplies no protocol description beyond the bare service name.
A search of vendor documentation, blogs, and forum or support threads as of an August 2026 search turned up no application, company, or product that generates traffic on this port. Third-party port-lookup aggregators (SpeedGuide, t1shopper, my-addr.com) only mirror the IANA name without adding any independent sighting data. No CVE is recorded in the NVD as of August 2026, and no malware or trojan association surfaced.
The repo's port-data.json (built from nmap-services) records an open-frequency of 0.000013 for 470/tcp (about 0.0013% of scanned hosts) and 0.000395 for 470/udp — both effectively negligible, consistent with a port that is registered on paper but essentially unseen in practice.

Primary use
undocumented; the IANA registry supplies only the service name with no RFC or protocol description
Other/unofficial uses
none identified in public vendor docs, blogs, or forum/support threads as of an August 2026 search
Security implications
no CVE recorded in NVD as of August 2026; no malware/trojan association found; negligible real-world prevalence indicates the port is essentially unused despite formal registration
Typically seen on
no host type, platform, or product documented; treat as anomalous if seen open [Unknown]
- Analyst note
- An open port 470 has no known legitimate application and negligible scan prevalence — treat as an anomaly warranting investigation rather than a normal service.
About port 470/udp.
Port 470/udp is registered by IANA under the service name scx-proxy, but no primary-source documentation describes what the scx-proxy protocol does or names any application that actually uses it; absent that confirmation, traffic on this port should be treated as unidentified rather than assumed safe to expose to the public internet.
The IANA Service Name and Transport Protocol Port Number Registry lists scx-proxy as dual-registered for both 470/tcp and 470/udp, assigned to Scott Narveson, with a blank Reference field and no registration date recorded in the live registry. IANA supplies no RFC, specification, or descriptive text beyond the bare service name.
A general web search for software, games, or services observed using UDP port 470 turned up only generic port-lookup-database mirror pages (SpeedGuide, t1shopper, my-addr.com, auditmypc, reddlegg) that restate the IANA name without describing any real client observed on the port. No vendor blog post, forum thread, or support document reporting actual traffic on 470/udp was found as of an August 2026 search.
SANS Internet Storm Center's combined port-470 page showed only low, background-level scanning as of the check date — single-digit source counts on the most recent day and a modest spike the day before — with a green threat-level indicator and no CVEs or user comments logged for the port.

Primary use
Unknown — IANA registers the name scx-proxy but supplies no RFC, specification, or vendor documentation describing its function
Other/unofficial uses
none found as of an August 2026 search [Unknown]
Security implications
SANS ISC shows only low/background scanning volume with a green threat indicator and no logged CVEs; no malware/trojan association could be confirmed or refuted from auditmypc.com's port-470 page
Typically seen on
Unknown — no credible community sightings of a specific application were found [Unknown]
- Analyst note
- The scx-proxy name and dual-registration are confirmed in the IANA registry, but its function, real-world applications, and malware status are unverified as of an August 2026 search; treat unexplained traffic on this port as unidentified rather than benign.
