Question: What is a domain DNS delegation?
Answer: For domains to work, they need to have DNS servers assigned. And those DNS servers are actually computers with a specific IP (a series of numbers that define where they are located). To avoid having to remember the IP, we give them a name. The name we assign to the DNS servers is what we call domain DNS delegations. For example, cdmon's first DNS server has the IP 35.189.106.232. To avoid having to remember the IP, we create the delegation ns1.cdmon.net and this name is a DNS delegation of the domain cdmon.net. When a delegation is correctly created, we can assign it to other domains so that they use the DNS server it points to.
NOTE: A DNS delegation is also called a host.
Q: How do I create a domain DNS delegation?
A: A delegation always depends on the parent domain. For example, ns1.cdmon.net depends on the domain cdmon.net, logically. The delegation must be created at the registrar that owns the domain cdmon.net. At cdmon, you have a control panel where you can access your domain management and create DNS delegations from your domains.
Q: Why isn't my DNS delegation working?
A: The propagation of delegations usually takes about 48 hours. On the other hand, for a delegation of any extension to be functional (to point to the IP assigned to it), you must create an A record in the DNS server configuration of the domain that points to the same IP as the delegation.
Q: Why doesn't ping return my DNS delegation?
A: The server does not respond because there is no A record created on your DNS server. For a DNS delegation to be functional (to point to the IP assigned to it), you must create an A record in the DNS server configuration of the domain that points to the same IP as the delegation.
Q: Why doesn't dig resolve my delegation?
A: It may be that the delegation is not active until an A record is created on your DNS server, or that the delegation has not yet propagated correctly. You must be patient, as propagation can take up to 48 hours to complete.
Q: What should I do if it doesn't work?
A: If you have created your delegation in the cdmon control panel and have created an A record pointing to the same IP, you just need to wait. If after 48 hours the created delegation does not work, you should contact our technical department and we will check that the configuration is correct.
Q: Why doesn't my DNS delegation for a .es domain disappear even after I delete it from the cdmon panel?
A: .es delegations cannot be deleted. You can delete them from your control panel, but they will remain in nic.es until they are no longer used for an indefinite period.
Q: Can I create DNS delegations for a .es IDN domain?
A: It is currently not possible to create delegations for a .es IDN domain. We recall that these are domains that contain special characters such as: ñ, ç, ó, ò, etc.
Q: Can I create DNS delegations for any domain?
A: It is currently not possible to create delegations for .eu, .ch, .nl, .de, .be, .co.uk domains.
