# WHATPORT(714)

## NAME

port 714 — IRIS over XPCS — A dead-end transport for the IRIS registry query protocol; RDAP won instead.

Protocol: TCP  
IANA registry

## DESCRIPTION

IRIS was the IETF's structured replacement for whois, and RFC 4992 defines running it over XPCS (XML Pipelining with Chunks for SOAP), which uses TCP port 714 with TLS. The design never saw meaningful deployment: registries kept port 43 whois and then moved to RDAP over HTTPS. There is essentially no production software listening here today. A hit on 714 is far more likely to be an unrelated service than an IRIS server.

## EXPOSURE

**Expose with care.** IRIS itself was a read-only query service, but an open 714 in practice means an unidentified listener — find out what it really is.

## CHECK

```sh
nc -vz TARGET 714
```
