Frequently Asked Questions

How long has Prefixx been in business?

Prefixx has been operating in the data center and networking space since 2007. Our team of dedicated professionals has extensive experience working with the 5 different regional internet registries.

Why does IPv4 address space have value?

Experts have been warning about IPv4 exhaustion since the late '80s, but companies still heavily rely on IPv4 to reach many parts of the Internet today. As Regional Internet Registries (RIRs) started running out of allocable space, a commercial transfer market was created to help sustain the growth of IT-infrastructure around the world. The price/value per IPv4 address is entirely driven by its supply and demand.

Should I buy or lease?

CapEx or OpEx. If your company is looking to fill a temporary resource shortage of IPv4, or facilitate for a project with a fixed lifetime, leasing might be the better option for your company. Buying might be a better option if your company is looking to secure addresses that will be statically assigned for a longer period of time

How many IPv4 addresses are left ?

The allocable address pool managed by the 5 Regional Internet Registries (RIRs) has been fully exhausted. A lot of allocated space is however still not in use, which has opened up an opportunity for companies to offer their space up for transfer through the IPv4 transfer market
