FAQ: DNS questions we get asked a lot

Why isn't my change live yet? Caching. Resolvers hold records for the record's TTL. Lower the TTL before planned changes.

Can I use a CNAME on my root domain? No — CNAME can't coexist with the MX and other records the root needs. Use an A record for @.

How many nameservers serve my domain? Three, geo-distributed and kept in sync. You edit the zone once and all three update.

Do I need IPv6 (AAAA)? Not required, but add it if your host supports it — it future-proofs your site.

How do I check what's actually published? Use dig name TYPE +short or an online DNS lookup, not your browser (which caches).

Can I host DNS here but my website elsewhere? Yes — point the A/CNAME records at wherever the site lives. DNS hosting and web hosting are independent.

What TTL should I use? 3600s (1 hour) is a good default; 300s when you're about to make changes.

Do you support DNSSEC? DNSSEC signs your zone and publishes a DS record at the registry; contact support if you need it enabled for a domain.

Can I delegate a subdomain to another provider? Yes — add NS records for the subdomain pointing at their nameservers.
