I'll second that. We have a little program that presents a rest api for

dns type stuff. I've never really used the reverse stuff, but it works.
Looks like it mostly returns a ptr record however. Not sure if that is what
you are looking for. https://github.com/fcambus/rrda is what we run, and
combining it with a query we use to monitory for SSL 5250 connections looks
like this.

WITH netstat AS (
SELECT *
FROM QSYS2.NETSTAT_INFO
WHERE local_port = 992
)
SELECT DISTINCT
(
SELECT COALESCE(
JSON_VALUE(httpresponse.responsemsg,
'$.answer.rdata' RETURNING VARCHAR(256)),
JSON_VALUE(httpresponse.responsemsg, '$.message' RETURNING VARCHAR(256)))
FROM TABLE (
SYSTOOLS.HTTPGETCLOBVERBOSE(
URL => CAST(
'http://172.24.1.36:8080/8.8.8.8:53/x/' CONCAT
TRIM(netstat.remote_address) AS VARCHAR(255)),
HTTPHEADER => CAST(
'<httpHeader includeErrorMsg = "true"></httpHeader>' AS CLOB(1K)))) AS

httpresponse) AS dns_lookup,

netstat.remote_address
FROM netstat
;

Gives me this

Is anyone aware of a way to translate an IP address returned by SQL to
its FQDN?

Although I haven't tried any of them, there are a number of web services
that offer DNS lookup's that should be relatively easy to consume from
SQL.

Here's one: https://dns-lookup.whoisxmlapi.com/api
