Prometheus exporter - interpret ::1 as 0:0:0:0:0:0:0:1

[NuxRo]

Hi,

If I configure the Prometheus exporter to allow requests from ::1 (ipv6 localhost, short form) it doesn't actually honour requests.

In the logs you can see entries such as:
Prometheus exporter received client request from: 0:0:0:0:0:0:0:1

Indeed, once you add 0:0:0:0:0:0:0:1 (ipv6 localhost, medium form) it starts working.

It's a minor issue, but nice to get sorted as most people are used to ::1.

The issue here not only lies in localhost, but any IPv6 address that can be written with a short form ::

MariaDB [cloud]> select value from configuration where name like 'prometheus.exporter.allowed.ips' \G
*************************** 1. row ***************************
value: 127.0.0.1,2a00:beef:feeb::15

2024-02-01 13:50:31,186 DEBUG [o.a.c.m.PrometheusExporterServerImpl] (HTTP-Dispatcher:null) (logid:) Prometheus exporter received client request from: 2a00:beef:feeb:0:0:0:0:15

marked as a bug. let's see if this can be fixed in 4.19.1.0/4.20.0.0
