Your are far by the best KZbinr for this kind of content as you don't just explain how to do something, you explain why to do things and how they actually work and not just saying put this here and there and it'll work. Love it!!! Shows you have put a lot of time into understanding the concepts properly.

[@V3LOXy]

Bit of advice, never use the :latest tag, look up the latest version tag (eg 2.4.2) and use that one instead. Always use a specific version and update in a controlled manner. You do not want to be in a situation where you've accidentally pulled a new version and your config files no longer work with that version. It will save you a lot of headache when something goes wrong or you have to migrate to a new server. You can backup your configs and docker file, but it does not ensure you that those config files will work on another device as you've not defined a version tag in your docker file, you may pull a completely different version. (I'm bad at explaining, please do look up why you shouldn't use :latest to understand it better)

[@GiorgioAresu]

So much this. So many people, and in so many big companies use tag latest and not all of them will listen or care enough to change

[@ヽノ-u4t]

There is a middle ground in between the `latest` tag or a tag pointing to a specific release. The current stable nginx release is version `1.23.3`, this version can currently be referenced by multiple tags like `latest`, `stable`, `1.23.3` or even `1`. If the images maintainers are competent, these additional tags will be updated on every release. To always use the latest nginx release of version 1.x.x, but never accidentially use the releases of another major release (2.x.x), just use the tag `1`. In a corporate environment, where all changes to the infrastructure have to be managed in a certain way, you hopefully want to control the update process and also the whole image registry and image build process anyways and push new releases to the registry yourself.

Hi Christian, interesting video. Just an idea: you could install a second Bind9 server and use the VRRP Protocol to cover the fallout of the first one. I‘ve done that with 2 Piholes on different servers with 1 virtual DNS address. If the first DNS server fails, the second one automatically takes command of the name resolution until the first one recovers 🤷🏼‍♂️. Works flawlessly! LG aus Luxemburg 🇱🇺

Don’t forget to add the docker networks to the internal ACL list, or you may end up like me wondering why portainer does not resolve 😅 BTW I use views to control who sees what. As a side note if you are privacy cautious do not use forwarders. Bind is capable to resolve on its own. You may need to setup a hint zone to speed things up a little.

Hey Chris, have you tried integrating PowerDNS for graphical management of DNS? It would be interesting to see it in a video. I have it set up in my lab with KVM/LXC and it's very useful.

Several days ago I tried to find good solution DNS server + simple web UI (preferrable is not 3rd party). And found that there is only one solution for this, called SnitchDNS. And decided that the best option is PowerDNS + 3rd party PowerDNS-Admin. Might Chris do not need UI for DNS management, because its his homelab with one user.

[@JasonSFuller]

@christianlempa a few notes: 7:26 Small nit-pick: it's "I. S. C." (Internet Systems Consortium) and not "I. C. S." You mentioned the incorrect acryonym a few times. 18:30 Try using dig (vs nslookup), since you're using BIND. IMHO (and as a former DNS admin for a large ISP), dig is more powerful and streamlined. For EL distros, you'll find it in the "bind-utils" package. Not sure about Mac or Debian-based distros like Ubuntu. 19:30 FYI, the reason why you can use .home, .corp, and .mail (but not .local) TLDs on your private network is because ICANN's board found they were already in prevalent use, and attempting to introduce them publicly would be "high-risk" due to potential name collisions. Originally, these TLDs were not listed in any standard (or RFC) and were technically off-limits (even though people still used them), at least until ICANN Resolution 2018.02.04.12 stated "the delegations of such high-risk strings would be deferred indefinitely." 21:15 Use named-checkconf and named-checkzone. There's probably a config option or extension in VScode to automate this, or you can just add a precommit githook. 31:30 I'm surprised you went with BIND over CoreDNS, since I know you're interested in Kubernetes and especially given your automation aspirations (check the ectd plugin for use outside of k8s).

Hi Christan, danke Dir vielmals, hat mir sehr geholfen. VG!

[@fanshaw]

I'd put a caching server like pihole on the inside and give out that IP to clients. That creates a consistent model for internal and external/3rd party domains: client->cache->[main cache]->authoritative server. This scales better if you go multi-site as you keep your authoritative systems in the data centre and put dumb caches out on sites and you can put your authoritative server somewhere nice like a DMZ, where it can publish out to the internet and do zone transfers to your ISP if required. Of course you can zone transfer to the DC (for things like dhcp dns registrations), but I think its neater centralise first if possible. You probably want to protect your primary DNS server with a DMZ which only allows outbound zone transfers to secondaries and doesn't answer queries itself. If someone hacks your DNS, you're toast.

[@Theborg72]

Thanks.. always as interesting, this is how I drive with bind9 I've been running Bind for a few years now and am completely satisfied. I send the questions to the Nginx reverse proxy which puts on the ssl certificate before servers.

[@Glatze603]

Hi Christian, I have one mir question: in the compilation of DHCP with Sophos XG and bind9, is it possible to get not reserved ip addresses from dhcp, this ip, hostname and domain is registered und bind9, so that this ip and this hostname can be resolved? I try to not reserve ip addresses and I do not want to create manuell bind enties. For me this works right now only with dhcp and unbound and only when both services run on the opnsense.

[@canadianwildlifeservice8883]

I am having good results since switching to Unbound. Be careful. When using a public resolver like Quad9 or Cloudflared, your ISP can still transparently proxy your DNS requests. This is referred to as a DNS leak. With Unbound, or Bind9, the DNS server on your network contacts different DNS root servers online and prevents DNS leaks. For some reason, I could not successfully use DoH or DoT (within AdGuard Home) without my requests being intercepted by my ISP's DNS proxies, as proven by the online DNS Leaktest websites. I would love to migrate from Unbound to Bind9 as BIND acts as an authoritative OR recursive DNS server, and not just a recursive DNS, and also use Pi-Hole or AdGuard DNS along with it.

[@philipp1960]

AddOn Question. When using nginx (for example to avoid maintaining all those certifiates on each system individually), all DNS Names would point to the proxy. if I ssh into the target like ssh DNSName, target is the nginx server, not the real server. Are you solving this issue somehow?

[@rdvqc]

Since you ask I have been running local bind, dhcp and smtp sevices for about 15 years. Originally I used an HP-UX system later moving to Centos and recently to Almalinux. I have owned a number of domains and master 'home.' variants for local use. Originally, when Internet connections were slower, it cut dns chatter on the Internet link by caching. The DHCP allows me to assign consistent IP's to my local devices and distribute DNS, gateway, NTP and other configuration. The DCHP on most ISP routers is pretty lame.

[@blackbarry45]

I use BIND9 on two raspberry pi3 for my public domains and a pihole on kubernetes for local ip's. my local domain is named the same as my public domain. in the past I've used bind9 with views for local and public resolution but it was much more comfortable to use pihole on my local net.

Nice introduction, thanks! Would like to implement something like this, but would miss the automatic DNS records that pfSense is providing via DHCP leases...

Hi David, this is exactly what I am trying to learn before switching from Unbound to Bind9. How to register dynamic and static DHCP leases and OpenVPN clients to the bind9 as DNS server. Have you ever got that done?
