Longest Domains

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.

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!

Special Mention Record-Breaker Single Word

Originally created in 2015, this domain broke the record of a long contested category, fiercly battled by many throughout the ages for claim to the longest word domain. A few years later it was abandoned, and it's namesake in .co.uk took back it's coveted spot. But only one can stay on top, and in April 2021 the domain was created anew and roared back to life to reclaim the crown for..


The absolute longest real single word domain name!



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.
