What Are HTTPS Records?

The Gandi interface allows you to add and manage HTTPS type records on LiveDNS. A HTTPS record is a derivative of SVCB recording, but instead of being generic, it is specific to the HTTPS protocol. HTTPS DNS registration makes it possible to indicate to the customer several parameters to facilitate connection to the server and thus reduce latency.

An HTTPS record use the same format than an SVCB record.

Alias mode

A HTTPS record can be used as an Alias for the Apex domain by setting the priority to 0. This method is supported by all DNS operators (unlike ALIAS or ANAME type records).

Service Mode

Service mode allow to defin which services are activated on HTTPS for a domaine name.

Add, modify and delete HTTPS records

By using the Simple View

If you use the Simple View of the LiveDNS interface to create, edit or delete an HTTPS record, you will have to complete the displayed form:

  • Type: HTTPS

  • TTL : The chosen TTL (Time To Live)

  • Name: The sub-domain, or Apex domain (@ is accepted) on which the service will respond

  • Svc Priority: Priority of use if several services. NOTE: If priority is set to 0, the record will be in Alias Mode, and will serve as an alias for the APEX domain, in place of a CNAME record (which do not work on apex domain).

  • TargetName: The domain name of the target alias (for alias mode) or alternative termination point (for ServiceMode).

  • Svc Settings: Settings like port, ALPN protocols (Application-Layer Protocol Negociation) available, etc.

By using the Advanced view

It is very important that the record format is respected :

name

TTL

IN HTTPS

priority

target

Settings Svc

serv

10800

IN HTTPS

10

serv1.example.com.

alpn=”h2,h3” port=”808”

Important

You don’t need to add the domain after the name as our DNS will add it automatically.

An example of what should a HTTPS record look like in advanced view when added to LiveDNS:

serv 10800 IN HTTPS 10 serv1.example.com. (alpn="h2,h3" port="808")

An example of an Alias for the Apex domain

@ 10800 IN HTTPS 0 www.example.com. (alpn="h2,h3" port="443")

The apex domain (example.com) is an alias for www.example.com, available on HTTP/2 and HTTP/3, via port 443
