The First Domain Name Ever Registered (and the 20 That Followed)

Before domain names: the HOSTS.TXT problem

In the early 1980s the network that became the internet, ARPANET, had a few hundred computers. Every one of them kept a copy of a single text file, HOSTS.TXT, that matched computer names to their numeric addresses. When a machine joined, someone at the Stanford Research Institute updated the master file and everyone downloaded it again.

That worked for hundreds of hosts. It was never going to work for thousands. The file grew daily, names clashed, and copies were always out of date.

The fix: the Domain Name System

In 1983 Paul Mockapetris designed the Domain Name System (DNS), with Jon Postel among the people shaping how it would be run. Instead of one giant file, names became a tree: a top level (like .com), then a name under it, each part managed by whoever owned it. That's the system you still use every time you type an address. If you want the modern version explained, our guide to what a TLD is covers the top of that tree.

symbolics.com: the first .com

The first top-level domains (.com, .edu, .gov, .mil, .org, .net) went live in January 1985. On 15 March, Symbolics registered symbolics.com and became the first company with a .com address.

Who were Symbolics?

• A spin-off from MIT's AI Lab, founded in 1980.
• They built Lisp machines: expensive workstations designed to run Lisp, the language most AI researchers used at the time.
• They were early network users, which is why they cared about an address before almost anyone else.

The irony is hard to miss: the first .com belonged to an artificial intelligence company, four decades before AI startups started paying fortunes for .ai domain names. Symbolics struggled when cheaper general-purpose computers caught up, and the company wound down in the 1990s. The domain outlived it.

The first 20 .com domains, in order

For the first two years, a new .com every few weeks counted as busy. These are the earliest registrations, as listed in widely cited registry history.

Notice who's on the list: computer makers, defence contractors and research labs. In 1985 the internet was a tool for engineers. Fewer than 100 .com domains existed by the end of 1986.

When famous companies got their domains

Some household names were early. Others waited years, and a few had to buy their name back from someone who got there first.

Several of those stories get their own post: the original names of famous apps, and how x.com went from a bank to a social network. You can check the registration date of any domain yourself with the domain age checker.

How much did the first domains cost?

Nothing. Registration was free and handled by hand. You asked, someone checked the name wasn't taken, and it was added.

When domains started costing money

• 1985–1995: free, funded by the US government. Mostly universities, labs and tech firms.
• 1995: Network Solutions, which ran registrations under contract, started charging, at $100 for two years.
• 1998–1999: ICANN was formed and competition between registrars began, so prices started falling.
• Today: a new .com typically costs around $10–20 a year, depending on the registrar and current offers.

The other firsts: .edu, .org, country codes and the first website

.com wasn't the only extension getting its first name in 1985.

The first website ran on a .ch address

Tim Berners-Lee published the first web page at CERN in 1991, on info.cern.ch: a Swiss address (.ch for Confoederatio Helvetica). The page explained what the World Wide Web was and how to use it. CERN has since restored it at its original address, so you can still visit it.

Country codes like .uk and .us arrived the same year as .com, which is why some of them have such long histories. Today there are well over a thousand extensions, from .io to .pizza, and you can search them all with the domain name search.

What happened to symbolics.com?

Symbolics the company faded, but its domain became a collector's item. In 2009 it was bought by XF.com Investments, a company that collects historic domains. Rather than build something new, the owner turned it into a small piece of internet history, explaining its place as the first .com.

Why old domains are worth money

• History: a 1985 registration is a story no new domain can tell.
• Age signals trust: an old, continuously registered domain is less likely to be a scam site, which is why checking how old a domain is is a common safety check.
• Short, real words: the earliest names were simple, which is exactly what buyers pay for today.

If you ever buy an older domain, look at its past too. Our guide on how to find out who owns a domain shows what public records can and can't tell you.

Strange facts about the early domain name system

The early internet was small enough that a few people knew almost everyone on it, and that shows in how domains were run.

• One person kept the list. For years, Jon Postel at the University of Southern California personally coordinated the top-level domains and number assignments. Colleagues joked that the internet's address book lived in his office.
• You needed a reason. Early registrations were expected to belong to organisations actually connected to the network, not people hoping to sell names later.
• There was no web to point at. A 1985 domain was used for email and file transfer. Websites didn't exist for another six years.
• Growth was painfully slow, then explosive. It took years to pass a few thousand .coms. In the mid-1990s, once the web and paid registration arrived, tens of thousands were added every month.
• Some early owners sold out big. Generic names registered for free in the early 1990s later sold for millions, which is why how much a domain name costs has such a wide answer.

Register the domain someone writes about in 40 years

In 1985, nobody imagined symbolics.com would be famous. Every brand that ends up on a list like this one started as a cheap registration for a small idea.

1. Brainstorm a name with the domain name generator or the business name generator.
2. Check every extension at once with the domain name search, or compare a shortlist with the bulk domain search.
3. Check the matching social handles with the username checker so your name is yours everywhere.
4. Register it and turn on auto-renew, so it never lapses.

Conclusion

Recap

The first domain name ever registered was symbolics.com, on 15 March 1985, by an AI computer company from MIT. It was free, one of fewer than 100 .coms that existed by the end of 1986, and the start of the system every website uses today.

Apple joined in 1987, Microsoft in 1991, Amazon in 1994 and Google in 1997. Domains stayed free until 1995.
