The Longest Domains on the Internet Today

The world has run amok with long domain names, with new registrations enjoying a resurgence that hasn't been seen for many years. So as an emergency precaution, I created this shrine to pay homage to only the most legitimate record-holding longest domains on the web today.

Super long domain names have virtually no utility, are almost impossible to remember, and are appreciated by only a few aficionados of the art. But this is what makes them special. Let's drive the distance and have some fun!

A domain name registration has a limit of 63 characters preceeding its extension. In calculating longest domain records, two criteria is used. First, both the dot and the TLD are considered in it's character count, pattern or purpose. Second, the domain's date of registration. Was that record type the first of its kind?

In this first section are my very own longest domains on the Internet. Each holds the first and current record in its length class. These domain names are so darn long that they barely fit on the screen!

Two Current Unbeatable Records


The absolute longest domain, with a total of 77 characters:



The longest ccTLD perfect palindrome using only the letter E:



Historical Records

The mind-blowing ingenuity it takes to brainchild a long domain name is just unfathomable. It requires a unique kind of view to appreciate these extreme names. But they have been around for longer than most would think. Since 1997, in fact. And then in 1999, it first became possible to register a 63 character name, which to this day is the limit to any registration.

In the spirit of honouring the pioneers of long domains, and as a nod of appreciation for inspiring mine own, this next section contains original record-holders.



The first longest real single word domain ever created in any TLD or ccTLD uses the dot-co.uk extension, and was registered in July of 1997. The name was lengthened for tourism purposes, actual place name is Llanfairpwll Gwyngyll.

This long domain name asks "Why the hell this domain name exists?" and the simple answer is given as "We don't know. Why not?". And why not indeed. This is the heart of these creations. The first and longest domain name ever made in the dot-si ccTLD also has a visitor counter and even offers a congratulatory medal. The 63 character from Slovania, registered in May 2020.

Coming Soon- Extreme Long Domains on the Web3 Blockchain!

In early 2020 a new DNS protocol called Handshake introduced the opportunity for open top-level domain creation on the blockchain. Of course, this only meant one thing: 63 character TLDs! Think .com, but waay longer!

Soon after Handshake, another entity called Unstoppable followed suit, wanting to make their mark in the Web3 namespace. Although they don't offer TLD creation, you are able to register a domain a whopping 252 characters long! This is almost as insane as the thought process behind wanting to own a long domain name to begin with.

I haven't tested how long of an SLD (second-level domain) can be created with a Handshake TLD, who knows, maybe even longer than 252 characters. Stay tuned!


There you have it. The longest domains in the world. And also on Earth!
