[moya2162]

Versions

• Pi-hole: 5.17.2
• AdminLTE: 5.21
• FTL: 5.23

Platform

• OS and version: Debian Bookworm

• Platform: ODROID HC4 (arm64)

Expected behavior

On Pihole's Dashboard summary tab, under top clients, client hostname, both ipv4 and ipv6 should resolve.

Actual behavior / bug

On Pihole's Dashboard summary tab, under top clients, client hostname, ipv6 specifically, does not resolve. Client is identified under Network tab. There appears to be an issue where not all hostnames are applied correctly to ipv6 addresses on the Dashboard.

Steps to reproduce

Steps to reproduce the behavior:

1. Go to "Dashboard" tab.
2. Scroll down to "Top Clients" and view hostnames. ipv6 not all ipv6 devices have hostnames resolved.
3. See error

Dashboard Tab

Network Tab

Additional context

Client hostnames resolved via EDNS0 method. All clients are able to resolve under network tab correctly for both ipv4 and ipv6 addresses. Dashboard appears to be bugged for some ipv6 addresses.

@moya2162 First you bring your Linux up to date with: apt update && apt upgrade -y then you first do: reboot and then you log back into your SSH and enter: pihole -up a new version came the pihole out your pihole is out of date

Linux is already up to date and pihole docker image was updated to latest version and issue remains. I'm not surprised the update did not fix it because the changelog did not indicate this issue would be fixed. This has been an issue for me for minimum last 3 months. There appears to be a disconnect with the dashboard tab not updating hostnames as fast as the network tab is able to identify it. The dashboard tab and query log eventually get the hostname resolved however it takes forever to do so. It should be instant like how the network tab can identify it.

Another data point to add is that my ftl db got corrupted and i had to delete it and rebuild it, but this issue still remains.

I can confirm this issue. I was closely watching logs the last weeks while checking out a different problem, thus logging in frequently, and indeed could not see resolved IPv6 hostnames on the dashboard very often. Since I did not encounter this problem when checking the actual logs, maybe it is just some display issue on the dashboard web-frontend?

EDIT: Corrected typos.

I'm unable to check this from an IPv6 perspective (I never did get around to setting it up on my network)

But if you're feeling adventurous - could you see if this is still an issue in our v6 beta? https://pi-hole.net/blog/2023/10/09/pi-hole-v6-beta-testing/

I just might snapshot the current system and upgrade to v6 and restore the snapshot afterwards. Maybe I'll have some time this weekend! ✌️

@bkodenkt were you able to check if this issue is reoccurring in v6?
