The process of reverse resolving an IP address uses PTR records. The reverse DNS database of the Internet is. The hostname or hostnames for the client IP are looked up using PTR queries.

DNS Overview of DNS zones and records. If I can figure out how to get dnscmd to uncheck the Update associated pointer (PTR) record I could then do that in batch. If it can be rechecked via dnscmd it should add the PTR records for each A record I put in the batch file. A PTR record (sometimes called a 'host PTR record') is what lets someone do a 'reverse' DNS lookup that is, they have your IP address and want to know what your hostdomain is.

Although it is possible to use includes to consolidate multiple domains that share the same set of designated hosts, domains are encouraged to use redirects where possible, and to minimize the number of includes within a single administrative domain. net lets you instantly perform a DNS lookup to check a domain names current IP address and DNS record information against multiple name servers located in different parts of the world. Can you recommend a coding standard? This is an ambitious project to guide people to an effective style of modern C and to provide tool to support its rules. This page defines configuration of a Sender Policy Framework (SPF) record for a domain and its mail servers.

The NS record specifies an authoritative name server for given host. Reverselookup Pointer records (PTR). As opposed to forward DNS resolution (A and AAAA DNS records), the PTR record is used to look up domain names based on an IP address. Pointer Record (PTR) Pointer records are the opposite of A and AAAA RRs and are used in Reverse Map zone files to map an IP address (IPv4 or IPv6) to a host name. Format name ttl class rr name 15 IN PTR The value '15' (the base IP address) in the above example is actually a name (an ownername or lefthand name) and because it does not teminate with a 'dot' BIND appends.

But this isnt just limited to DNS, but how do you set up your Send Connectors, Receive Connectors, how both connectors relate to DNS and the SMTP banner, and how to allow your Connectors to advertise TLS to the outside world. So, one of these cases may lead you to bulk PTR records creation in the future when you realize that you need this kind of record(s). I will try to simply show you, how to do that very quickly using the least administrative effort because using DNS Management console is not very convenient and fast method (you need to create each records separately by hand). Note: Your existing setup will be different, but the example names and IP addresses will be used to demonstrate how to configure a DNS server to provide a functioning internal DNS. You should be able to easily adapt this setup to your own environment by replacing. PTR (kurz fr Pointer) Resource Records ordnen im Domain Name System einer gegebenen IPAdresse einen oder mehrere Hostname(s) zu. Sie stellen damit gewissermaen das Gegenstck zur klassischen Zuordnung einer oder mehrerer IPAdresse(n) zu einem gegebenen Hostname per A oder AAAA Resource Record dar.
