AdGuard Home Setup - Remaining Steps

Complete these steps when you're on the local network.

1. Setup Wizard

Access: http://192.168.86.149:3053

Configure:

Admin interface: All interfaces, port 3053
DNS server: All interfaces, port 53
Create admin username/password

2. Configure Upstream DNS (Quad9 DoH)

Settings → DNS settings → Upstream DNS servers:

https://dns.quad9.net/dns-query

Enable: Parallel requests for faster resolution

3. Add Blocklists

Filters → DNS blocklists → Add blocklist:

List	URL
AdGuard DNS filter	(enabled by default)
OADB	`https://raw.githubusercontent.com/ookangzheng/dbl-oisd-nl/master/dbl.txt`
Steven Black	`https://raw.githubusercontent.com/StevenBlack/hosts/master/hosts`

4. Configure Router

Set your router's DNS server to: 192.168.86.149

This makes all devices on the network use AdGuard for DNS.

5. Verify

# Test DNS resolution
dig @192.168.86.149 google.com

# Test ad blocking (should return 0.0.0.0 or NXDOMAIN)
dig @192.168.86.149 ads.google.com

# Test internal domain
curl http://dns.schweitz.internal/

Delete this file after setup is complete.
