VPS for DNS Server: Full-Control DNS Hosting on Your Own Infrastructure
Relying on third-party DNS means trusting them with every domain lookup your users make — and trusting they will not go down during a critical moment. An AnubizHost VPS running your own DNS server gives you complete control over zone files, resolution behavior, DNSSEC signing, and query logging. No third-party dependencies, no arbitrary record limits.

Why Self-Host Your DNS
Managed DNS providers like Cloudflare and Route53 are convenient, but they see every query your users make. For privacy-sensitive operations, this metadata exposure is unacceptable. A self-hosted DNS server on an offshore VPS keeps your zone data and query logs entirely under your control.
Self-hosted DNS also removes feature restrictions. Managed providers limit the number of zones, records, and queries per month. On your VPS, you host as many zones and records as you need, with no per-query billing and no artificial caps.
For authoritative DNS specifically, self-hosting gives you control over TTLs, DNSSEC configuration, CAA records, and advanced record types (SSHFP, TLSA, LOC) that some managed providers do not support. Your DNS, your configuration, your policy.
DNS Software Options
BIND 9 is the most widely deployed DNS server globally. It handles authoritative and recursive DNS, supports DNSSEC signing, dynamic updates, and split-horizon views. It is the reference implementation and supports every DNS feature in existence.
PowerDNS separates authoritative and recursive functions into two daemons (Authoritative Server and Recursor). Its database backends (MySQL, PostgreSQL, SQLite) make zone management programmable — update DNS records with SQL queries or API calls instead of editing zone files.
Unbound is the best choice for recursive/caching DNS. It is lightweight, secure by default, and supports DNS-over-TLS and DNS-over-HTTPS. For ad blocking, pair Unbound with Pi-hole or AdGuard Home on the same VPS for network-wide filtering.
High Availability and DNSSEC
DNS is critical infrastructure — if your DNS goes down, everything depending on it becomes unreachable. Deploy at least two AnubizHost VPS instances as primary and secondary DNS servers. BIND and PowerDNS support automatic zone transfers (AXFR/IXFR) between primary and secondary, keeping both servers synchronized in real time.
Place your DNS servers in different physical locations for geographic redundancy. If one data center has an outage, the other continues resolving queries. Most domain registrars let you specify 2-4 nameserver addresses, and resolvers will automatically fail over to the responding server.
DNSSEC signing protects your domains from DNS spoofing and cache poisoning attacks. Both BIND and PowerDNS support automated DNSSEC key management, including key rollovers. Sign your zones, publish DS records at your registrar, and your visitors can verify that DNS responses are authentic and untampered.
Deploy Your DNS Server
DNS servers are lightweight. A 1 vCPU / 1 GB VPS handles authoritative DNS for thousands of zones and millions of queries per day. For recursive DNS serving a network or organization, 2 vCPU / 2 GB provides ample cache space and query processing capacity.
Install BIND, PowerDNS, or Unbound via your distribution's package manager, configure your zones and records, update your domain's nameserver records at the registrar, and your self-hosted DNS is live. The entire process takes under an hour.
AnubizHost VPS includes DDoS protection, which is critical for DNS servers — they are frequent targets for amplification attacks. Our mitigation infrastructure filters attack traffic while allowing legitimate DNS queries through. Run your DNS on infrastructure built for reliability.
