User Datagram Protocol

Today we will explore the User Datagram Protocol. First, we will explain its purpose, and then we will see its history and how it was created. Finally, we will explore its applications and the differences between UDP and TCP/IP.

The purpose of the User Datagram Protocol 

UDP stands for User Datagram Protocol. It is a key component of the Internet protocol suite. It allows us to link various Internet services with minimal latency and loss tolerance.

The User Datagram Protocol speeds up communication by allowing data to be delivered before the recipient agrees. As a result, for time-sensitive communications such as DNS lookups, Voice over IP (VoIP), video, or audio transfers, User Datagram Protocol is the preferable technique.

DNS CAA record

The DNS CAA record was first defined in 2013, and from September 2017, Certificate Authorities are obliged to review it before issuing any certificate. So, let’s clarify things a little bit more about it.

DNS CAA record – Definition

The CAA (Certification Authority Authorization) record is a Resource Record in DNS (Domain Name System) that lets domain owners to specify which CAs are authorized to issue a certificate for the domain name. 

Certification Authorities (CAs) are organizations that are authorized and able to issue certificates for domain names, for instance, SSL, TLS, or other certificates.

IPv6

IPv6 is the most recent edition of the Internet Protocol, intended to replace IPv4. The Internet Protocol version 4 scarcity is a significant problem, but the world continues to move forward, so it’s time to let it go. The final IPv4 countdown has begun. Let’s look at what IPv6 has to offer and how to make the most of it!

IPv6 – what does it mean?

IPv6 is the sixth iteration of the Internet Protocol’s IP address. IPs are a set of rules that a device must follow when sending and receiving data from a host to a destination. We’ll need a list of recognizable hosts, their locations, IP addresses, and a communication path.

Returning to IPv6, it has been around since 1995! The strange thing is that there has been a scarcity of IPv4 addresses, as well as other issues. Despite this, the majority of organizations continue to use the earlier IPv4 standard. Since 2017, it has been an Internet Standard (IETF) to anticipate an increase in IPv6 usage in the near future.
