For those that run a homelab with DNS and DHCP, are you using IPv6? I'm running BIND and debating if I need to configure IPv6 just to future-proof myself. I'm not seeing any issues, at least any that I notice.

Also, I know little about IPv6, so I admit I need to do some learning.

So I recently used a #sledgehammer where a #scalpel was needed.

I've got an #HP DL80 Gen9 with the iLO license, but without the #FlexibleLOM card... so to access the iLO I have to have an ethernet cable plugged into the first ethernet port.

Problem is, no matter what I tried in #Webmin or #NetworkManager, every reboot would re-enable that port... which would then get a IP via DHCP (even when I'd disabled it in nm...), which would mean #Zabbix would pick it up as a client and add it.. meaning every time a disk got a little "backed up", I'd get two alerts, and this machine has 12 very old SATA drives in it.

Tired of messing with the damned thing, I finally got out the sledgehammer....
....and blacklisted HP's #OUI from the #DHCP server.

No IP, no extra client created in Zabbix, and only the normally-annoying amount of alerts.

I'll #fsck with it for real, later...

I finally shut down my last remaining Windows 2003 R2 server that was serving as my DHCP and primary DNS server (the secondary DNS server, also Win 2K3 R2, was shut down a few weeks ago).

Goodbye old friend. You were flawless for many years. I've moved onto Kea.

Remember, you too can mute #WeezysServer if you don't wanna deal with my bullshit.

We have pi-hole running on our network, combined with ublock origin on the browsers of our personal devices, we're getting page loading speeds we've not had in years.

However, my partner's work laptop (over which we have NO ADMIN CONTROL) keeps kicking him from accessing files or servers he needs.

We put him in his own group with no AdList in the hope it just.. doesn't do anything, like, acts as a tiny speed bump on the road to the internet. However, its still happening. The only hint we have is a message in "pi-hole diagnosis" which says
"warning in dnsmasq core,
Ignoring domain <work domain> for DHCP host name <business device name>"

Which the documents suggest means the device is trying to claim its own name on the DHCP and its not allowed to and frankly...

What the fuck does that even mean?

Frage zu Heimnetzwerken:
Wenn ihr Geräten in eurem #Netz eine feste IPadresse zuweisen wollt, wie macht ihr das?
Ich mache das immer am Gerät selber. Also #IP, #Gateway, #DNS. Alles manuell einstellen. Das macht natürlich den Vorteil von #DHCP zunichte.
Es gäbe ja nun auch die Möglichkeit die feste IP auf dem DHCP Server zu konfigurieren. Also auf Basis der MAC Adresse.

2. Frage: Wenn ein Gerät mal per #WiFi mal per Kabel im Netz ist: Gleiche IP verwenden oder unterschiedliche?

If you were setting up your home #network, and wanted to make sure that important, foundational, yet lightweight services Just Kept Going, how would you run them?

For example, I'm thinking about #DNS and #DHCP for the hosts that actually provide the more user-visible network #services ... so "run them as #VM/#containers on your #homelab hosts" isn't a viable option: what provides the DNS *for* those hosts?

I quite like the idea of a pair of low-cost & low-spec mini-PCs.

What would you choose?
