Out of all the tools available to home labbers, I think local DNS servers are the most powerful. I’ve used many variants, from PowerDNS to Technitium, Unbound, BIND9, and CoreDNS, each with its own quirks but providing the same core experience. Part of the reasoning behind self-hosting and home lab use is control, and what better to gain control over than DNS?

After all, without DNS, the networking layer of your home lab wouldn’t work. It’s the control plane for how data is passed around your home lab, how traffic leaves (and enters), how devices and services are named for discoverability and identity, and a host of other things. The other thing that I’ve come to realize is that having a single DNS server isn’t enough. There are many situations where you’d want local control over DNS, and troubleshooting is hard enough without having to rely on a single server to do all the work.

Self-hosting a DNS server makes your searches faster and more secure.

Why bringing DNS under your control is important

DNS makes or breaks your home lab configurations

DNS is often thought of as the phone book of the internet, but it’s more than that. It’s an ever-evolving repository of routes, lists, and knowledge of how to reach the disparate resources of the connected world. CDNs use complicated DNS to serve you content from the fastest location, it enables broadband, 5G wireless, and more.

With that much potential power, of course, you want it inside your home lab. Whether it’s for locally-resolvable domains to make service discovery easier, DNS blocks for bad actors, noisy devices, and ads, or more complex uses, your home lab is better with a local DNS server that you control.

Having a DNS server you control gives you plenty of upsides:

Control of uptime: The double-edged sword of self-hosted DNS servers where you’re not dependent on ISP or third-party DNS servers, but that also means you’re responsible for keeping your server online
Privacy: Using an encrypted DNS stops your ISP and everyone else logging your queries
Better performance: Local lookups are fast
Control of domains: Use local domains to resolve your services and devices
**Security: **Blocking ads, malware, known bad regions and more at the DNS level keeps your home lab safer

DNS servers you self-host could be authoritative, providing the list of domain records your home lab contain. It could be recursive, querying other authoritative sources, or a DNS blocker, or a load balancer for DNS queries at scale.

PowerDNS

The good news is that setting up your own DNS server doesn’t take long

Whichever DNS server you decide to use while ditching external resolvers and those of your ISP, most of them are fairly quick to set up. PowerDNS is an exception, as you have to build the database backend and a few other things on the way, but most packages are ready to go, requiring nothing more than setting your router to capture all requests on port 53 and pass them on to your new self-hosted DNS server.

Setting up encrypted queries using DNS-over-TLS (DoT) and DNS-over-HTTPS (DoH) takes only a few more minutes, sometimes requiring plugins, but many DNS servers now offer these as standard features. That prevents snooping of your queries, and it’s highly recommended in this age, where all information is monetizable. There is a small performance hit if you’re going directly to authoritative servers with DoT, but it’s worth it for the privacy it affords.

You’ll want more than one

It’s not fun when your DNS server goes down

If DNS is the backbone of your home lab, what happens when it goes down? Services won’t resolve, you won’t be able to use the internet, and you’ll spend many hours trying to get things back up and running. You’ll want redundant DNS servers, whether that’s two Pi-holes synced with Nebula Sync and Keepalived to make them appear as a single IP for your devices to point at, a Technitium cluster, or whatever.

Secure your DNS servers; they don’t need to be accessible from untrusted subnets or from the public internet.

Along with two clustered or mirrored DNS servers to provide failover, you might want multiple layers of DNS technologies in your preferred combination:

DNS filtering (Pi-hole, AdGuard Home, Technitium)
Recursive resolver (Technitium, Unbound, PowerDNS, CoreDNS)
Split-horizon DNS for resolving home lab services internally
Conditional forwarders for specialized environments
Encrypted queries for everything going to the internet

You’ll also want to decide on if you’re going to use a domain name you own, or **.lab, **or another local domain for your lab (avoid .local, that’s reserved for mDNS usage). Being consistent from the start makes things easier once you scale, and DNS can give you the worst of headaches. Don’t forget some monitoring solution to spot anomalies like noisy devices sending lots of queries to a single domain or misbehaving IoT things, and if you integrate your DNS with DHCP, you can have hostnames automatically resolve without manual entries, making it feel like magic.

Technitium

Filtering of DNS requests

Pi-hole might be the best-known DNS sinkhole, but AdGuard and Technitium can also do this, using block lists to remove unwanted ads, trackers, telemetry and malware at the DNS level before it makes it to your network. Add geofencing to this mix to ensure that regions known for malware, spam, and attacks cannot connect to your IP address, making your home lab and home networks safer.

Pi-hole

Adding a recursive resolver

Using a recursive resolver like Unbound means that instead of forwarding queries to upstream providers such as Quad9, Cloudflare, and Google, your DNS server "walks the chain" and resolves thequery itself. It does this by going to the root servers and working backwards down to the authoritative name servers that host those domains. This is best combined with a DNS filter for security and privacy, and you can use the resolver as a conditional forwarder for your domain as well.

Unbound

And don’t forget about conditional forwarders

Conditional forwarders use a rules-based system to send DNS queries to the resolver you specify. If you’ve got a home lab and main network, you might want queries for home.lab to go to one DNS server, while all other DNS traffic goes upstream or to your recursive resolver. This gives you more control over what resources different devices can access, and is a huge benefit for home lab users.

Split-horizon DNS for local and public records

Self-hosting services that need to be public-facing, like blogs, Nextcloud, or GitLab, bring a new problem. How do you resolve nextcloud.mydomain.com to your public IP address from outside your network, but to the private IP address when connected to your home network? You don’t want to suffer hairpin NAT or routing issues, and the solution is to set up split-horizon.

This is a secondary set of DNS records that override specific services to give you local domain names on the LAN and public IPs when you’re outside it. Then you set up conditional forwarding from the main DNS server you are using to point at those secondary DNS records when that domain is used, and it should be pingable from both the local and external zones.

I ensure that my home lab has clients on my internal network, which are responsive and not exposed externally.

DNS makes your home lab flow

Knowing how DNS works, how to control it, and how to divert it for home lab use is incredibly powerful. It gives you a better understanding of the networking layer, how the internet works, and how to securely route traffic through your network as you want. Don’t get too locked into using one DNS solution, I’ve found that combining multiple ones to get the results I need is a better option, and makes troubleshooting easier as I can decide if it’s issues with name resolution, forwarding, or DNS blocking.
