DNS is a Domain Name System, distributed naming system for resources connected to the Internet. In CDmon Static DNS means the resources that it points to are assigned constant, non-changeable IP (as in opposition to Dynamic DNS system). DNS servers are responsible for resolving domain names to IP addresses associated with them. Basically if the domain is to be found on internet it must have DNS servers (at least 2) assigned to it. DNS server "tells" the domain where it should direct requests to load a web page, access email server, FTP, etc.

1.- CDmon DNS servers

First thing to do is to make sure your domain has CDmon static DNS servers assigned to it. If it's not the case, it won't be possible to manage DNS records using our Control Panel.

Following you will find a list of our static DNS servers (IP that are constant):

  • ns1.cdmon.net:
  • ns2.cdmon.net:
  • ns3.cdmon.net:
  • ns4.cdmondns-01.org:
  • ns5.cdmondns-01.com:

Usually it is not necessary to provide DNS IP addresses, nevertheless you might find the list handy when necessary. 

2.-How do I learn what DNS servers are assigned to my domain?

If you want to know what DNS servers are assigned to your domain, in your Control Panel access the "List of domains" tab then "Manage" the domain you want to inspect and click "Manage servers" and the list of assigned servers appears.


3.-How to modify DNS servers assigned to my domain in CDmon?

If the domain isn't registered with CDmon, you can still check the DNS servers using the WHOIS tool on our website.

It is recommended to assign CDmon DNS servers if your domain is hosted with us. In case where your domain doesn't have CDmon DNS servers assigned to it (ns1.cdmon.net, ns2.cdmon.net, ns3.cdmon.net) we advise you to change it with the current registrar. Bear in mind, changing DNS servers may take up from 24 to 48 hours to propagate over the Internet.

To change DNS servers in CDmon Control Panel go to domain management page and follow the "Manage Servers" link as seen in the following image.


In the following page select "New DNS servers" (default) and enter the new values in the fields below. Remember to save the data!

Should you have more than two servers to enter, you can add more fields with the " + Add new server" link.



Sometimes yoo may receive an error upon modifying the servers:

  • The entered DNS cannot contain the dash character (-): a domain cannot start or end with a dash.

  • The entered DNS server contains non-valid characters: non-valid characters are:  # & ! () ?¿, etc.

  • The DNS server you have entered does not exist. You should create it first as a delegation/host of the domain: To create a delegation and use the servers, first the delegation must be created, then DNS servers may be changed.

  • At least two DNS servers are needed: the minimum number of DNS Servers for a domain is 2. If you have entered more than 2 and you get this message, please check that you have not entered duplicates.

  • None of the servers is new: you are entering exact the same servers that are assigned to the domain.

  • The entered DNS server cannot be null: one of the fields is empty, you need to enter the DNS servers you wish to assign and click on “Save Data”.

  • Could not make any changes. Please, try again or contact us: this error message is displayed at different situations and may be due to a temporary error. Please repeat the operation and if the error persists, you may need to contact us to solve the issue.
