Reverse IP Domain Checker
What is Domain?
The name of your website which visitors or people type in the browser URL section to visit your webpage or site. This name is known as Domain.
For example, if your website is a house or a building, then the domain name will be its address.
Example: Intel.com, firstly registered its domain in 1986. Till the present day, their website age is more than 30 years.
What is an IP?
Internet Protocol, an abbreviation of IP is a set of rules which govern the format of data sent through the internet of the local network.
An IP address consists of numbers and these numbers are separated by periods.
IP addresses are mathematically produced and assigned by the IANA (Internet Assigned Numbers Authority). When anyone registers a domain on the internet, they have to pass through a domain name registrar, who pays a small amount of fee to the ICANN to register the domain.
DNS and IP Address
DNS stands for Domain Naming System. IP Address and DNS are both similar in their working system. DNS and IP both are the naming systems to address the namespaces which are allocated for the entries in the network. DNS provides an entity name, which is based on some standard rules and regulations. While the IP addresses are the actual location from where the entities are located.
What is reverse DNS?
A reverse DNS lookup is the query DNS of a domain name that is associated with a given IP address. This fulfills the opposite of the most commonly used forward DNS lookup, in which the system of DNS is required to return the IP address.
IETF (Standards From the Internet Engineering Task Force) recommends that every domain should have the capability of a reverse DNS lookup. But DNS lookups are not the hard requirement as reverse lookups are not crucial for the normal function of the internet.
How does reverse DNS work?
The reverse DNS lookups query the DNS servers for the PTR record, if the PTR record is not present on the server, then the server cannot resolve the reserve lookup. The IP addresses are stored with their segments reserved by the PTR records, which they append “.in-addr.arpa” to that.
For example, a domain has an IP address of 192.0.2.1, the domain’s information will be stored by the PTR under the 1.2.0.192.in-addr.arpa.
In IPv6, which is the latest version of the Internet Protocol (IP), the PTR records stores the information within the “.ipa.arpa” domain instead of “.in-addr.arpa”.
The server cannot resolve the reverse lookup if the PTR record is not available or missing.
PTR records store IP addresses with
Use of reverse DNS lookups:
Reserver Lookups are commonly used for email servers. Before bringing any email into the network, the email servers check and see whether the email message came from a valid server or not.
If the email server does not support the reverse lookups or the server is highly unlikely to be genuine, then the message from any of these servers will be rejected. Spammers often use the IP addresses from a hijacked machine, so there will be no PTR record in presence. Or they might use a dynamically assigned IP address which may lead the server domains with highly generic names.
Further, we have also mentioned some other benefits and usage of the Reverse DNS lookup below:
Reverse IP Domain Checker:
Reverse IP Domain Checker checks and verify the IP address which points to the web servers and discovers the other sites which are hosted on the same IP address. You have to just enter the name of the domain to find the Reverse IP lookup.
