Add and edit DNS records

DNS records route traffic for your name: they point it at a website, direct your email, and hold verification values. You manage them in the DNS Records card on the Web tab, which appears once DNS is active.

Supported record types

my.box supports these record types:

  • A points your name at an IPv4 address.

  • AAAA points your name at an IPv6 address.

  • CNAME points your name at another hostname.

  • MX directs email for your name to a mail server.

  • TXT holds text values, often used for verification.

Add a record

Choose Add DNS Record and fill in the form:

  • Host: the part of the name the record applies to. Use @ for the name itself, or a subdomain like www.

  • Type: one of the types above.

  • Value: where the record points (an IP address, a hostname, or text).

  • TTL: how long the record can be cached, in seconds. It defaults to 3600, which is a sensible value if you are unsure.

  • Priority: shown only for MX records, where a lower number is tried first.

Choose Add DNS Record to save. my.box confirms when the record is added. A new or edited record usually takes effect within an hour, so give it time before testing. Enter values carefully: the exact value you type is what gets published, so a typo in an IP address or hostname will simply not work.

Edit or delete a record

Use a record's actions menu to edit or delete it. Deleting asks you to confirm, since a deleted record cannot be recovered.

One rule to know: your name must always have at least one DNS record. If you try to delete the last one, my.box asks you to add a replacement first.
