What is a PTR file?
A pointer (PTR) record is a type of Domain Name System (DNS) record that resolves an IP address to a domain or host name, unlike an A record which points a domain name to an IP address. PTR records are used for the reverse DNS lookup. An A record should exist for every PTR record.
How do I check my PTR record?
Two Methods to Check PTR Record and Reverse DNS Lookup

Are PTR records necessary?
You need a PTR record because many mail servers will reject email that comes from a mail server without one. After all, the goal is to keep the spam out of your inbox.
Where are PTR records stored?
PTR records are not stored within your domain zonefile, they are stored in a zonefile usually managed by your service provider or network provider. Some service providers provide an interface where you can create the PTR record yourself, others require you to submit a support request to create or change the PTR record.
Which type of zone do you find a PTR record in?
Reverse DNS zone
What is DNS type A record?
A Records. A Records are the most basic type of DNS record and are used to point a domain or subdomain to an IP address. Assigning a value to an A record is as simple as providing your DNS management panel with an IP address to where the domain or subdomain should point and a TTL.
What is the command for reverse DNS lookup?
nslookup command
How do I find the hostname of an IP address?
Querying DNS
- Click the Windows Start button, then “All Programs” and “Accessories.” Right-click on “Command Prompt” and choose “Run as Administrator.”
- Type “nslookup %ipaddress%” in the black box that appears on the screen, substituting %ipaddress% with the IP address for which you want to find the hostname.
What is the command for nslookup?
Go to Start and type cmd in the search field to open the command prompt. Alternatively, go to Start > Run > type cmd or command. 1. Type nslookup and hit Enter.
What is DNS forward and reverse lookup?
With a forward DNS lookup, the DNS is queried for the IP address of a certain hostname. A reverse DNS is exactly what you’d expect. It’s where the hostname of a certain IP address is queried. Basically, a reverse DNS lookup returns the hostname of an IP address.
What are the types of DNS servers?
3 types of DNS servers—DNS Resolver, DNS Root Server and Authoritative Name Server. 10 types of common DNS records—including A, AAAA, CNAME, MX and NS.
How do you do a forward and reverse lookup?
The Reverse DNS Lookup Process Using rDNS, the IP address is reversed and then the in-addr.arpa is added to the end. For example, if we use the IPv4 address of 67.227. 187.136, using rDNS, it would become 67.in-addr.arpa. This method of reverse DNS resolution of an IP address uses a PTR record.
What records will you find in a forward lookup zone?
Resource records with IP addresses that correspond to DNS domain names or services that is stored in the zone. Forward lookup zones are usually used for computers to find resources that you manage or control and forwarders (or root hints) are so that your computers can find everything else in the world.
What is the difference between forward lookup and reverse lookup?
Question: What is the difference between forward and reverse DNS lookup? Forward DNS lookup is used to convert the human meaningful name (domain name) which is in easy to understand format to computer meaningful name (IP address), however reverse DNS lookup works in reverse way to convert IP address to domain name.
Which records are kept in the reverse lookup zones?
Reverse lookup zones are used to resolve IP addresses to a hostname. For reverse lookup zones to work they use a PTR record that provides the mapping of the IP address in the zone to the hostname.
What is difference between forwarder and conditional forwarder?
Conditional forwarders are DNS servers that only forward queries for specific domain names. Instead of forwarding all queries it cannot resolve locally to a forwarder, a conditional forwarder is configured to forward a query to specific forwarders based on the domain name contained in the query.
What happens if you don’t configure DNS forwarding?
Without forwarding, all DNS servers will query external DNS resolvers if they don’t have the required addresses cached. This can result in excessive network traffic.
What is the purpose of a DNS forwarder?
In Domain Name System (DNS) terms, a DNS forwarder is a DNS server that is used to forward DNS queries for external DNS names to DNS servers outside that network. It does it to DNS queries that it cannot resolve locally, meaning DNS queries that it has no personal knowledge of.
How many DNS forwarders should I have?
Have at least Two Internal DNS servers In small to large environments, you should have at least two DNS servers for redundancy. DNS and Active Directory are critical services, if they fail you will have major problems. Having two servers will ensure DNS will still function if the other one fails.
Should I disable root hints?
So, unless the Windows server is going there just to exercise itself, there should be absolutely no reason to use root hints unless it’s to resolve an illegitimate domain.
Should I use root hints or forwarders?
The best use of root hints is on internal DNS servers at lower levels of the namespace. Root hints should not be used for querying DNS servers outside your organization; DNS forwarders are better equipped for performing this function.
Should I install DNS before Active Directory?
DNS is an important prerequisite of Active Directory. Without it, Active Directory will not function, or should we say, you can’t install or promote a server to a domain controller without having a DNS server either locally on that server or somewhere else on your network.
Is domain controller same as DNS?
TCP/IP uses IP addresses to communicate, and a DNS server resolves oblect to IP addresses for all the transmission based items your network needs to communicate with, like PC’s, servers, printers, etc. A domain controller on the other hand holds all of the other information about everything in your network.
Should a domain controller point to itself DNS?
– If a DC is hosting DNS, it should point to itself at least somewhere in the client list of DNS servers. – When referencing a DNS server on itself, a DNS client should always use a loopback address and not a real IP address.
