Under “PTR Records” click the plus sign to add a new record. Within the zone you just created, add a PTR record. NOTE: This must be the same group of name servers that the domain(s) you will apply the configuration to are assigned. Give the configuration a name, and select a group of name servers from the dropdown menu it should apply to. Click the plus sign below the table to add a new set of nameservers.ĤC. If the nameservers do not match, follow the steps below before proceeding to step 5. These must match the DNS Made Easy name servers that you requested delegation to in Step 2. After you have added your reverse DNS domain into the DNS Made Easy system you are provided with a list of name servers that your reverse zone is assigned. Enter the zone you received from your ISP (or owner of your mail server’s IP block). Create Reverse DNS ZoneĪt the top of the Control Panel, Click the DNS Menu and select Managed DNS from the drop down.ģB.
You can request they set up the reverse DNS for you and they will host your PTR records. If your provider will not delegate the reverse DNS to DNS Made Easy then there is no reason to continue this tutorial.
Usually, an ISP or hosting company will only delegate the reverse DNS if you have 256 IPs (a full class C) or more, but some companies have been known to make an exception. You can see which nameservers are authoritative for your domain here.
You will need to provide your ISP with the nameservers for your domain.
Then you will need to ask your ISP to delegate reverse DNS to your DNS provider much like your registrar delegates any requests for your DNS information to your DNS provider. If your reverse DNS domain is not configured within DNS Made Easy yet, the name servers you provide for delegation may be different. This is the domain we create, this domain is defined within the DNS Made Easy and assigned to, thus those are the name servers the delegation was performed to. Please note, DNS Made Easy’s delegation is already performed in this screenshot.ĭNS Made Easy’s IP block is a full class C so the syntax of our delegation is 147.94. Check Your Zone Syntaxĭouble check your delegation syntax with a Reverse DNS Trace. NOTE: You must create your domain within DNS Made Easy using the exact same syntax your ISP or hosting provider used to delegate it. If your IP block is smaller than a class C then your zone might look like this “27/1.” or “0-25.1.”. Meaning this reverse DNS zone would handle the reverse DNS for IPs 192.168.1.1 to 192.168.1.256. So “1.” would be the reverse DNS for the 192.168.1 class C. The numbers that precede the “in-addr.arpa” are actually your IP block with the octets reversed. This zone is actually a special reverse DNS domain that ends in “in-addr.arpa”.
NOTE: You can determine the owner of an IP address by performing a WHOIS search on the IP in question using this free tool.Ĭontact your ISP (or whoever owns your IP block) and request a zone for your mail server’s IP address. You will need to find out who owns your IP block (usually this is your ISP or hosting provider).
