DNS Lookup

A reverse IP lookup checks an IP address pointing to a web server and searches for other sites known to be hosted on that same web server.

What is a DNS lookup?

DNS WHOIS lookup is a process that allows internet users to determine the owner of a particular domain name. This information is stored in a database called the WHOIS database, which is maintained by the Internet Corporation for Assigned Names and Numbers (ICANN).

One of the primary uses of DNS WHOIS lookup is to determine the availability of a domain name. When a user wants to register a new domain, they can use a WHOIS lookup tool to see if the domain they want is already registered. If the domain is available, the user can then proceed with the registration process.

DNS WHOIS lookup can also be useful for finding out who owns a particular domain. This can be helpful for a variety of reasons, such as verifying the legitimacy of a website or trying to contact the owner of a domain for business or legal purposes.

In addition to providing information about the owner of a domain, DNS WHOIS lookup can also reveal other details about the domain, such as the name servers associated with it and the date it was registered. This information can be useful for technical troubleshooting and for understanding the history of a domain.

Overall, DNS WHOIS lookup is an important tool for anyone who works with or is interested in the inner workings of the internet. It allows users to easily access information about domain ownership and other details, which can be useful for a variety of purposes.

DNS lookups tool involve converting domain names into IP addresses, which are easy-to-remember numbers. These numbers are used by computers to communicate with each other on the Internet, but humans have difficulty remembering them and they can change from time to time when the network configuration changes.

A helpful way to think of a DNS lookup is similar to the contact list on your phone. However, it is a special one that has everybody's name without them telling you their number. If they get a new number, your phone automatically updates it. You don’t need to remember each of your contacts' numbers, but searching for their names is quick and easy. When you select their name to make a call, your phone will automatically use their current phone number.

What DNS record types can be looked up?

For example, www.example.com could host a website (A record), send and receive email (MX record), and access VoIP (SRV record) with its DNS records. There are many different types of DNS records used for different purposes. Each of these services uses a different DNS record type.

A Records

A record storing IPv6 addresses known as an address v6 or IPv6 DNS record.

MX Records

Using DNS records, Mail Exchangers determine which server handles email for a domain name.

NS Records

DNs for nameservers contain the authoritative nameservers for domain names.

TXT Records

In DNS records, text records are used to store notes, but they are most commonly used to store configuration settings for a variety of services, such as SPF records for determining which email servers are allowed to send email from a domain or verification codes for webmaster applications.

SOA Records

Domain name start of authority DNS records store meta-data about a domain name, including the domain's administrator contact email address and when its DNS configuration was last modified.

CAA Records

A DNS record for Certificate Authority Authorizations indicates what certificate authorities are allowed to issue certificates for a domain.
