Management of DNS zones

Requirements:

What are the different types of DNS entries?

Following you can find information about the most common types of DNS entries:

  • A : Allows you to link a domain name with an IP address (ipv4) (www.online.net. IN A 212.27.35.195).
  • AAAA : Allows you to link a domain name with an IP address (ipv6) (irc.online.net. IN AAAA 2a01:e0b:1:f:2d0:b7ff:fea9:4da8).
  • CNAME : allows for the mapping between a DNS name and another DNS name (sql.domaine.ext. IN CNAME mysql1.online.net.)
  • MX : Allows to set the responsible mail server for a domain (online.net. IN mx.online.net.).
    The DNS name MUST be an IPv4 and can not be an IP address or a CNAME.
    Priority defines the time in which the servers are contacted if there are more than one
  • TXT : This record can store a string of 1024 characters.
  • SRV :

This registration enables automatic discovery services, this type of record is reserved for expert users ONLY.

Attention: Errors in the configuration of your DNS zone may result in the unavailability of your website or emails. The modification of the DNS zone is a function that should only be used by experts.
We don't provide support for web hostings or domain names with DNS zones modified by the user.

Zone management

You can manage multiple versions of your DNS zones at Online.net.

Each modification on an existing DNS zone will launch the creation of a new temporary zone. Once you have finished your modifications, you will be able to create a permanent zone from the temporary zone and to set it as active to allow its usage on the Internet.

Following you will see an image of the management interface:

(1) : Zone selection. You can navigate between your different zone versions to modify them and to set them as active.

(2) : Here you can manage the “options” of the zone. You can edit the name or set it as active.

(3) : DNS entries. Here you can add / modify your different DNS entries in your zone.

How to modify a zone?

If you want simply to add or delete an entry in the zone, you just have to make the changes in the current zone, the one that is shown to you.

Once the modifications are done, you have to click on the button Create a new version that is available in the options of the zone (2).

Finally click on Set as active and wait for the propagation of the zone.

How long takes the propagation of a DNS zone?

The DNS zone is normally propagated depending of the TTL (or Time To Live).
This is the default refresh information during which other DNS servers on the Internet keep the information about your DNS zone in their cache.
By default this value is 24 hours (86400 seconds).

You can edit the TTL to your convenience, knowing that the new TTL will not be applied until the next reload, at the end of the current TTL. On the Internet it is generally recommended to set a minium TTL of one hour (3600 seconds). Many DNS servers will not respect your values if your TTL is below that value.

The provisioning of your DNS zone is done instantly. 
If you want to verify that your changes have been taken into account, you can query direcly the servers ns0.online.net and ns1.online.net.

Advanced - ''BIND'' configuration mode

To facilitate the management of your zones, reserved for experts, we provide you the option to send and download your DNS zone in the BIND format.

This is the format mostly used for the configuration of a BIND DNS Server.

This allows you to re-import your Zones if they were previously in this format, or if you are used to it.

In the form; you can directly copy / paste the desired content.

If you want to recover your current zone, click on the button Download
