What is my IP address?

Your IP address is and is an IPv4 address. That means it follows the Internet Protocol version 4, which is the most common version of the Internet Protocol in use today. Due to the shortage of IPv4 addresses, IPv6 is being deployed to replace it. Find my IPv6 address

What is a Reverse DNS?

A reverse DNS is used to find the associated domain for a given IP address - it's the reverse process of a DNS lookup. Not all IPs have a reverse DNS, since it requires a PTR DNS record to be set.

What is a CIDR?

CIDR stands for Classless Inter-Domain Routing and is a method used to group IP addresses. It's written as IP/number, where number is known as the network mask. It represents the number of leading 1-bits in the subnet mask.

What is an AS and ASN?

AS stands for Autonomous System, while ASN stands for Autonomous System Number. Each AS is operated by an entity (like an ISP, an individual, schools...) and operates a list of IP subnets. An AS is identified by a number, the ASN.

What is the HTTP version?

The HTTP protocol has evolved and improved over the years. HTTP/1.1 is battle-tested, but old and inefficient. HTTP/2 reduces latency by using techniques like compression and multiplexing requests over a single TCP connection. HTTP/3 is the latest version and uses QUIC over UDP to further reduce the latency.

What is TLS?

TLS stands for Transport Security Layer and is the successor of SSL (Socket Security Layer). Those terms are often used interchangeably, but nowadays TLS is largely predominant. It uses cryptography to secure the connection between a client and a server, like for HTTPS. The latest version of TLS is 1.3.

What is a User Agent?

A User Agent is an HTTP header used to determine and/or identify the type of client that made an HTTP request. For web browsers, it contains the browser name and version, OS name and version, type of device and more. Tools like cURL or crawling engines can also be identified using this header.
