Since the establishment of the RIPE NCC, 5,000 Local Internet Registries (LIRs) have closed (see: From 80 to 8,000 - The Growth of the RIPE NCC). We wanted to find out why. Many of them were probably victims of the burst of the dotcom bubble. But how many? And which countries were mostly affected? How many closures were the results of mergers? We’ve got answers below.

How many LIRs that started up during the dotcom bubble have since closed?

If we define the dotcom bubble as the three years between 1999 and 2002, then 978 of dotcom LIRs have since closed. This accounts for 36% of all closed LIRs. The reason for closure could be anything from not paying invoices, stopping their business, renaming, merging or being taken over (see some more details on reasons for closure below). As you can see in the image below, around 50% of those LIRs were located in the UK, Germany, Russia, Italy and the Netherlands.

What are the reasons for closing an LIR?

It is difficult to reliably determine the reasons why LIRs stop doing business. To get an idea, we looked at a sample of all LIRs that opened in the UK during the dotcom bubble and that have since closed. This might not be a representative sample, but it adds up to 15% of all closed LIRs that opened during the dotcom bubble years. It at least gives an indication of the various reasons why LIRs closed.

In the image below you can see that almost 50% of all closures were caused by non-payment. Nearly one-third of the LIRs that closed, merged with or were taken over by other LIRs. Around 20% of the LIRs closed for other reasons, often because they decided to stop their business.

How long were closed LIRs operational?

We also looked at the time LIRs were operational before they closed. In the image below, you can see that the majority of LIRs were open for less than five years. But there are also a number of LIRs that were in operation for over 15 years. Some of them were probably taken over or merged into other organisations and might still be around in some form. The average time that a now-closed LIR was a member of the RIPE NCC is 4.3 years.

We also looked at those LIRs that opened during the dotcom bubble. Their average life-span was very similar: 4.6 years. That means that the dotcom generation does not behave that different from others; we just saw many more signing up during those days.
