Dynu gives you full control over all the DNS configurations for your domain names.
You can log onto the control panel to manage your DNS records.
To add a PTR record in the control panel, you may follow these 3 steps.
Step 2
Go to
DNS Records
to add a PTR record. The screenshot below shows how to add a PTR record for dynu.biz.
Node Name The reversed IP address followed by the reverse DNS zone. For an IPv4 address such as 192.0.2.1, the node name would be 1.2.0.192.in-addr.arpa.
Type Choose "PTR - Pointer".
TTL How long the server should cache the information. The TTL is set in seconds, 60 is 1 minute, 1800 is 30 minutes.
Hostname The fully qualified domain name that the IP address should resolve to, for example mail.dynu.biz. This hostname must have a corresponding A or AAAA record pointing back to the same IP address for forward-confirmed reverse DNS.
Step 3
Check if your PTR record has gone into effect using the DNS Lookup tool. Enter 1.2.0.192.in-addr.arpa as Hostname, and choose "PTR - Pointer" as Type.
What is a PTR record?
PTR records (Pointer Records) are used for reverse DNS lookups. An IP address can be associated to a domain or hostname. This is opposite to what an A/AAAA record does for forward lookup zones. PTR records go into reverse DNS zones which end with .in-addr.arpa for IPv4 or .ip6.arpa for IPv6 addresses. It is used to verify if a server name is actually associated with the IP address from which it is sending.How to add a PTR record?
