The first domain name ever registered was symbolics.com, claimed on March 15, 1985, by a Massachusetts computer maker called Symbolics. It was the very first commercial .com address on a system that, in those days, was free to use and barely populated. The domain still exists today, kept alive as a kind of internet landmark.
What was the first domain name?
symbolics.com. Registered on March 15, 1985, it edged out a small field of early adopters to become the first .com domain in existence. At the time, registering a domain involved emailing the people who ran the naming system and asking nicely — there was no fee, no web form, and certainly no rush, because almost nobody had a computer that could reach the network anyway.
The web did not exist yet (that arrived in 1991), so symbolics.com was not pointing at a website in any sense we would recognize. It was an address on a network used mostly by researchers, defense contractors, and universities. For more on what came before browsers, see our internet history timeline.
What was Symbolics?
Symbolics was a computer manufacturer that built specialized workstations called Lisp machines — high-end computers designed to run the Lisp programming language, which was the language of choice for artificial intelligence research in the 1980s. These were expensive, powerful machines aimed at AI labs and research institutions, not home users.
The company was a spinoff from MIT’s AI Lab and rode the first big wave of AI optimism. When that wave broke and cheaper general-purpose hardware caught up, the market for dedicated Lisp machines collapsed, and Symbolics declined through the late 1980s and 1990s. The company is long gone in its original form, but its domain name outlived it by decades.
How did domain names start? The birth of DNS
Before domain names, computers on the network were tracked in a single text file called HOSTS.TXT, maintained centrally and copied to every machine. As the network grew, that approach buckled — one shared list could not scale.
The Domain Name System (DNS) was designed to fix this. Paul Mockapetris invented DNS in 1983, publishing the foundational specifications that defined the hierarchical, distributed naming scheme we still use. The system rolled out across 1983 and 1984, introducing the top-level domains — .com, .org, .net, .edu, .gov, and others — that organize the namespace to this day. By the time symbolics.com was registered in 1985, the plumbing was fresh and the field wide open.
Why DNS mattered
DNS let humans use memorable names like symbolics.com while computers quietly translated them into numeric IP addresses behind the scenes. It is the reason you type a name instead of a string of digits, and it is one of the unglamorous-but-essential pieces of infrastructure, alongside the first email system, that made the modern internet usable.
What were the first six .com domains?
In 1985, only a handful of .com domains were registered. The earliest registrants were almost all technology companies — the only organizations with both the hardware and the reason to be on the network. Symbolics was first, followed over the following months by other computing and electronics firms.
| Order | Domain | Registered |
|---|---|---|
| 1 | symbolics.com | March 15, 1985 |
| 2 | bbn.com | April 1985 |
| 3 | think.com | May 1985 |
| 4 | mcc.com | July 1985 |
| 5 | dec.com | September 1985 |
| 6 | northrop.com | November 1985 |
The names read like a roll call of 1980s computing: BBN was the contractor behind much of ARPANET, DEC made the era’s dominant minicomputers, and Thinking Machines Corporation (think.com) built massively parallel supercomputers. The whole first website was still six years away.
When did domains become paid?
Domains were free for a decade. That changed in 1995, when Network Solutions — the company contracted to run .com, .net, and .org registrations — began charging for them. The original fee was on the order of $100 for a two-year registration, with a portion initially set aside to fund internet infrastructure.
Charging money transformed domains from a clerical formality into an asset. Once names had a price, they had a market, and the gold rush began. People started registering domains they thought companies would eventually want, and the practice of domain speculation was born almost overnight.
How big is the domain market today?
Enormous, though exact figures vary by source. There are hundreds of millions of registered domain names worldwide across thousands of top-level domains — far beyond the original handful of TLDs from 1985. Premium domains routinely change hands for six and seven figures, and a few headline sales have reportedly crossed the eight-figure mark.
The landscape is also far more crowded. Where once there was just .com and a few siblings, there are now hundreds of generic top-level domains. If you want a sense of just how much the network has ballooned since 1985, our piece on how many websites there are covers the scale. You can even build your own version of that growth in the clicker game on our homepage, which turns one click into an entire internet.
Does symbolics.com still exist?
Yes. After the original company faded, the domain changed hands and is now maintained as a kind of internet museum and historical curiosity, explicitly because of its status as the first .com ever registered. It is a small monument to a moment when the commercial internet was so empty that being first cost nothing but an email.
Frequently Asked Questions
What is the oldest domain name?
symbolics.com is the oldest registered .com domain, claimed on March 15, 1985. It belonged to Symbolics, a maker of Lisp machines for AI research. The domain still exists today, preserved largely because of its historical status.
Who invented the domain name system?
Paul Mockapetris designed the Domain Name System in 1983, creating the hierarchical naming scheme and the top-level domains like .com and .org. DNS replaced a single shared host file that could no longer keep up with the growing network.
When did you have to start paying for domains?
Domain registration was free until 1995, when Network Solutions began charging a fee, initially around $100 for two years. Putting a price on names created a market and kicked off domain speculation.
Why was symbolics.com the first domain?
Symbolics was a technology company building Lisp machines, so it had both the hardware and the motivation to be on the early network. When DNS opened up commercial registration, Symbolics simply got there first, on March 15, 1985.
How many domains exist today?
There are hundreds of millions of registered domains across thousands of top-level domains, though precise counts vary by source and change constantly. That is a vast leap from the six or so .com domains that existed at the end of 1985.
