I have AdGuard Home on my PC. When I turn pc off, I need to switch DNS server on router (for me I need to turn off 'strict order' in OpenWRT settings).
I dont wanna go to settings every night and every morning.
So I built simple DNS server which has my AdGuard Home as first upstream and Cloudflare as second upstream server. And when my PC is down it uses Cloudflare. When my PC is up it uses AdGuard Home on it. Automatically. That's what I needed.
Note
You must create config.json to run the server (see Config)
- Download binary for your platform from releases tab
- Rename to dns-switcher (optional)
- Run:
./dns-switcher
docker run -p 53:53 -v ./config.json:/app/config.json -d ghcr.io/misshanya/dns-switcherservices:
dns-switcher:
container_name: dns-switcher-server
image: ghcr.io/misshanya/dns-switcher
ports:
- "53:53"
volumes:
- ./config.json:/app/config.json
restart: unless-stoppedRequirements:
- Go 1.24+
git clone https://github.com/misshanya/dns-switcher
cd dns-switcher
go build -o dns-switcher .And run as usual binary
./dns-switcherConfigure it via config.json
You can set the listen address and upstream servers. Example config:
{
"address": ":53",
"upstreams": [
"1.1.1.1:53",
"1.0.0.1:53"
]
