Unsure whether Anycast DNS is worth the cost for an SMB site

Anycast routes the same IP globally to the nearest DNS PoP. For a local NL site the difference versus good unicast DNS is small, but for international visitors, mail-delivery latency and DDoS resilience the gap is real.

Try this first

  1. 1First ask yourself: if 90 percent of visitors are in NL and BE, a solid unicast zone (Versio, Antagonist) is fine.
  2. 2If you have international clients, a SaaS product or mail that needs to arrive fast worldwide, Anycast (Cloudflare, NS1, Route 53, deSEC) easily shaves 50 to 150 ms off TTFB in distant regions.
  3. 3For DDoS, Anycast absorbs attacks across PoPs, unicast DNS folds faster under volumetric attacks.
  4. 4Check the provider supports DNSSEC, ALIAS/CNAME-flattening and API access, those are the usual migration breakpoints.
  5. 5Migration cost itself is low: export the zone as BIND format, import at the new host, change NS records at the registrar.

When to bring us in

If you have a use case where every millisecond matters or you are a DDoS target, we can set up Cloudflare or NS1 and run the migration without downtime.
