Portable IP address space
Each organisation wishing to exchange traffic with other organisations over an internet exchange needs their own portable IP address space. There are two ways to acquire portable IP addresses from Regional Internet Registries (RIRs), wuch as RIPE.
- PI Assignment – Smaller organisations will normally choose to apply for a “Provider Independent” IP address assignment. This is requested from a RIR through the organisation’s regular ISP using the RIPE-356 form.
It should be noted that PI assignments smaller than 256 IP addresses are not generally routable on the Internet. In addition, it is not guaranteed that PI assignments of 256 IP addresses or greater are universally visible on the Internet.
- RIR Membership – For larger organisations, the normal procedure is to become a RIR member and be allocated a much larger block of “Provider Allocated” (PA) address space. Further details on RIPE NCC membership can be found at the RIPE NCC New Membership page.
INEX does not provide IP addresses or AS numbers for its members.
