Each network range (IP block list) requires one DNS zone to be configured. For an example, if you have /22 IPv4 network range, you need to separate it into 4 DNS zones for each /24 sub-network. There is no limit on the number of PTR records which can be configured into the DNS zone.

The web-based control panel allows our customers to monitor the propagation over all data centers in real-time.
