    It is not necessary. Most computers do not require a PTR record.

          It is very safe, to maintain privacy, PTR DNS records verify your sent emails using reverse DNS lookups. To verify the authenticity of incoming mail, your mail servers typically check PTR records.

            There are some systems that only store the IP address, not the domain name. PTR records assist in identifying the source of traffic in such a scenario.​
