How to get your ASN and IP Prefixes

In order to use BGP with your transit IP Provider and then connect to Perú IX (PIT Peru sac), the first thing you will need is to have your own ASN and IP prefixes, granted by LACNIC (the RIR in charge of Latin America) or another RIR.

There are two large groups before the indicated modalities that will depend on the type of organization that requests the resources:

  • IP resources for ISPs (the most common and which we cover in this article)
  • IP resources for end users (e.g. universities, non-ISP companies , etc.)

The process and costs to obtain IP resources may vary depending on the type: ISP or end user (end user)


You can apply to two modalities:

  • ASN, IPv4 Prefix and IPv6 Prefix (long path, waiting list)
  • ASN and only IPv6 Prefix (fast path)

Request ASN, IPv4 Prefix and IPv6 Prefix for ISPs

This mode is only available to those ISPs that have neve

It is important to mention that IPv4 prefixes can still be requested, with a maximum of / 22, for organizations that have never previously received IPv4 Prefixes by LACNIC, but will now enter a Waiting List, so the process may take several additional months. so we call it the long way. I advise you to complete the procedure as soon as possible to save time.


Note: these are unofficial times, and should only be considered as a time estimation guide.

When making the request for IPv4, you will be asked for your current prefix of IP addresses assigned by your current Internet Provider. If your prefix is ​​greater than a / 30 (that is, for example a / 29, / 28, / 27, …) you must ask your provider to sub-assign this prefix to your organization. If your IP prefix is ​​equal to or less than / 30 (that is, / 30, / 31 or / 32) this additional step is not necessary.

Request ASN and only IPv6 Prefix (fast path)

Due to the current phase of the IPv4 address depletion process, the quick option is to request only the ASN and IPv6 Prefixes, that is, to be an IPv6 only ISP. For

It is important to mention that IPv4 prefixes can still be requested, with a maximum of / 22, for organizations that have never previously received IPv4 Prefixes by LACNIC, but will now enter a Waiting List, so the process may take several additional months. so we call it the long way.
