DNS Sinkholing: Blocking Malware Domains at the Network Level

Sun, 09 Nov 2025 16:00:00 +0000

Almost every nasty thing a compromised device does starts with a DNS lookup. Malware phones home, a phishing link resolves a lookalike domain, a tracker beacons to an analytics endpoint — all of it begins with “what’s the IP for this?” Which makes DNS the single best chokepoint on your whole network. Block the name and the connection never happens; no firewall rule per IP, no deep packet inspection, no certificate gymnastics. That’s DNS sinkholing, and on a home or small-business network it’s the highest-leverage security control I run.
