Click a type to see what it does.
Points a hostname to an IPv4 address. The most fundamental record — it is how browsers find your web server.
The IPv6 equivalent of an A record, pointing a hostname to a 128-bit IPv6 address.
Aliases one hostname to another. Useful for pointing www or subdomains at a primary host without duplicating IPs.
Tells the world which servers accept email for your domain, with priority ordering for failover.
Free-form text used for SPF, DKIM, DMARC and domain-ownership verification.
Delegates a domain to the nameservers that hold its zone. Change these to move DNS providers.
Zone metadata: the primary nameserver, admin contact and serial number that tracks changes.
Maps a specific service and port (like SIP or XMPP) to a target host, with priority and weight.
Every MilesHost domain includes managed anycast DNS with a 100% uptime SLA — changes propagate in seconds, not hours.
Fast, secure hosting for businesses of every size — backed by humans who pick up the phone.
