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.

Did you know ISC had a #DNS Hackathon recently? It was hosted by #RIPE_NCC , #dnsoarc , and #Netnod in Stockholm on March 14-15. We proposed a project, the DNS Zone Viewer, to integrate another DNS implementation (besides #BIND 9) with Stork, our graphical management interface.

Read more about it at isc.org/blogs/2025-dns-hackath !

I started a discussion with fellow #sysadmin about updating #BIND / #named config to migrate from the overly permissive allow-update {…} stanzas to the more restricted update-policy {…} stanzas using targeted grant statements.

The idea being to allow the #acme client to only be able to update (add / delete) _acme-challenge TXT instead of any record in the zone.

Old:

allow-update {
TSIG_KEY_NAME;
};

New:

update-policy {
grant TSIG_KEY_NAME name _acme-challenge.example.net TXT;
};

ETA: Okay the below is fixed, but why would db.root not update when everything else does?

(it's on Debian)

okay this is weird

the root hints file I have diffs identically to the one I just pulled down from the internic as a sanity check (other than the last updated date which is also weird)

but I'm getting this regardless:

named[1252171]: checkhints: b.root-servers.net/A (170.247.170.2) missing from hints
named[1252171]: checkhints: b.root-servers.net/A (199.9.14.201) extra record in hints

(and similar for the IP6, elided for space)

why

Oh my goodness, how did I miss that in ES7 you can use a closure as a method. Goodbye `bind()`, you will not be missed :)

e.g.,

```js
class A {
b = () => console.log(this)
}

const a = new A()
a.b() // A { b: [Function: b] }

const c = a.b
c() // A { b: [Function:b] }
```

Nice! :)

**Edit**: Be careful with this. See this note by @marsup: mastodon.social/@marsup/113799

MastodonMarsup (@marsup@mastodon.social)@aral@mastodon.ar.al Respectfully, this looks like an anti-pattern. `b` won't be part of the prototype, potentially preventing some meta programming, and you're going to get a new `b` for each instance of that class, consuming that much more memory for each instance you hold.

My dear sysadmin Federati with home labs and internal networks!

Our internal network has grown and now we want internal DNS resolution for local network stuff. It's a combo of bare metal and docker services, mostly from one host but not limited to it.

I really, really don't want to touch BIND again so I'm in a bind (badum-tss) and looking for suggestions. Any Linux based / containerised options for DNS on LAN?

Suggestions and boosts welcome!

Finally got around to setup a #FreeBSD server. There was a huge need for more beastie fun 😎
Currently serves #DNS in a #Jail via #Bind
Another #Jail is on the way for some internal hosting via #Nginx :freebsd:

Currently looking for some more ideas on how to leverage the system some more.

What do you guys run on your #BSD servers?

(Most of my services are currently containerized on a #Docker #Linux server)
