DynDNS does not offer free DNS service anymore.

We could not find any information for the permanent free service on the web site.

Now, they offer a free trial service for 30 days instead of it.

They allowed making two free domain names in each free account.

Now, you should pay for this service, or using a small router could be an alternative.

However, domain names you made before this change are available.

and receive sensitivity was done on AP side.

The results came out as follows:
