Frequently Asked Questions

What is a RIR?

A RIR, short for Regional Internet Registry is an organization that's responsible for management and allocation of IPv4, IPv6 and ASN Internet number resources within a specific region.

What is supernetting?

Supernetting is the aggregation of multiple internet ranges of the same IP class. Supernetting is done to decrease the overhead of the continuously growing routing tables, and the physical limitations of the devices using them. Supernetting can only be done with contiguous IPv4 or IPv6 addresses.

What is a subnet mask?

A subnet mask is a 32-bit number that is used to divide IP addresses in a class, a common procedure often done in larger allocations for specific assignments or security reasons.

How many IPv4 addresses are left?

Most Regional Internet Registries (RIR) such as ARIN (in 2015) and RIPE (in 2018) have already exhausted their resources and are now recycling old IP pools and recovering unused space within their region.

How long does it take to transfer IPv4 addresses?

The duration of the transfer depends on the corresponding Routing Internet Registry region but consider that any process may take between 10 to 30 days to complete.

Why lease IPv4 addresses instead of buying?

IPv4 addresses are expensive and continue to become more expensive every day. If you have a temporary need for IPv4 addresses or your company does not wish to spend capital on them, then leasing may be the right solution for you. Prefixx offers short- and longterm rentals.

How much does Prefixx charge per transaction?

Prefixx charges a flat fee of 10% on any buying or selling transaction.
