Merge pull request #3247 from proddy/dev

fixes #3246 - Inconsistent display of IPv4/IPv6 addresses in web UI

CHANGELOG_LATEST.md

@@ -27,6 +27,11 @@ This release is based on the latest Espressif/Arduino core version 3. It brings
 - LED stayed off on a healthy system when "Disable LED" was unchecked
 - Ethernet MAC address changed with the new SDK, breaking DHCP reservations (currently disabled)
 - "IPv4 nameserver" showed an IPv6 address when IPv6 was in use
+- the Network status page showed at most one IPv6 address and could hide the IPv4 DNS server entirely. It only read the link-local address, so a dual-stack host's ULA and global addresses were never reported, and it only read two of the three DNS slots, which are shared between IPv4 and IPv6. It now lists every address the interface holds, each labelled with its IPv6 scope, and every configured DNS server [#3246](https://github.com/emsesp/EMS-ESP32/issues/3246)
+- the Gateway was only ever reported for IPv4, so on a dual-stack network the IPv6 default router was missing from the Network status page, `show system` and the MQTT `info` topic. Routers are learnt from router advertisements rather than configured, so all of them are now listed [#3246](https://github.com/emsesp/EMS-ESP32/issues/3246)
+- `show system` had the same gaps, reporting a link-local IPv6 address only and a single IPv4 DNS server. The WiFi and Ethernet sections now list every IPv6 address with its scope, and every DNS server labelled with its own family [#3246](https://github.com/emsesp/EMS-ESP32/issues/3246)
+- the Access Point status page reported whichever interface happened to be active, so with the AP down it showed the station's IP and MAC address under an "Inactive" heading. It now always reports the soft-AP's own details, and shows `none` when the AP isn't running
+- the MQTT `info` topic published no addresses at all when connected over Ethernet, and over WiFi only an IPv4 address plus a link-local IPv6 one. Both interfaces now report their MAC, IPv4 address and gateway, every IPv6 address and every DNS server. Note that `IPv6 address` is now an array, and `IPv4 DNS Server` is replaced by a `DNS Server` array that covers both families [#3246](https://github.com/emsesp/EMS-ESP32/issues/3246)
 - HA Discovery warning on Uptime after EMS-ESP boot due to NTP not ready
 - hc/control setting for UI800 thermostats [#3181](https://github.com/emsesp/EMS-ESP32/discussions/3181)
 - solar module switches [#3223](https://github.com/emsesp/EMS-ESP32/issues/3223)
