IPv4 Allocation and Renumbering Policies
InterLIR follows the NRPM 4.2.2 policy guidelines when dealing with IPv4 allocations and renumbering. This means that any ISP without a direct allocation or assignment from ARIN can initially request an allocation of up to a /22 block. Of course, all of this is subject to ARIN’s minimum allocation size requirements, so no wishful thinking on giant IP blocks without the paperwork.
For ISPs that have no direct allocations, assignments, or even re-allocations, InterLIR automatically qualifies them for a /24 block. The best part? These ISPs don't have to jump through hoops proving they’re efficiently using any previous IPv4 space-because, well, they don’t have any. If they want a bigger slice than a /24, they just need to show how they’ll use the extra addresses wisely, staying within the bounds specified in NRPM 4.2.4.3. It’s like getting a bigger pizza by promising to actually eat all the slices.
Now, if an ISP holds re-allocations or reassignments, they need to demonstrate efficient use of their IP assets. InterLIR checks if their utilization meets the standards spelled out in NRPM sections 4.2.3 and 4.2.4. No slacking here-if you’ve got the addresses, you better be using them smartly.
When it comes to documentation for those initial requests, InterLIR likes to keep things neat and transparent. You'll need to provide detailed lists that cover every nook and cranny where your IP addresses live and breathe:
- A breakdown of CIDR prefixes and ranges assigned to dynamic pools, including the service type such as DSL or wireless, the city or region being served, peak utilization percentage at busy times, and how many customers each pool supports. Basically, prove you’re not just hoarding IPs like digital dragons.
- A roster of IP addresses or subnets that are statically assigned to customers, complete with the names of those lucky customers. InterLIR wants to know who’s who in your IP zoo.
- An inventory of IP addresses used for web hosting, along with at least one customer domain name per IP. Because everyone likes to know where their websites crash-oops, we mean, live.
- A list of IP addresses or subnets assigned to internal equipment and infrastructure, alongside the corresponding hostname or device name for each. InterLIR insists on clarity-this isn’t just IP space, it’s your network’s backstage pass.

IPv4 Allocation Efficiency Standards
InterLIR takes IP allocation seriously, insisting on solid proof that your address space isn’t just gathering dust. You need to show that at least half of each individual allocation is buzzing with activity, proving you're squeezing good value out of every IP. But wait, there's more-combine all your allocations, and at least 80% of those IPs should be actively doing their thing too. No black holes here!
When it comes to handing out IPs to your customers, transparency is key. If you're assigning chunks of eight or more contiguous addresses, you’ll have to provide detailed reassignment info using SWIP or RWhois. For those smaller assignments-less than eight addresses-you get a bit of flexibility but still must supply reassignment data, either as text files or spreadsheets. Keeping track is part of the game.
Dynamic pools also want love. You’ll need to whip up lists showing which CIDR prefixes or ranges are used for these pools, tagging each with its service type, whether that's DSL, wireless, or something else, as well as the city or region served. Add peak utilization percentages and how many customers enjoy service from each pool, and you’ve nailed the transparency game.
Web hosting IPs don't get to hide either. InterLIR wants a clear list tying each IP address to at least one customer domain hosted there. And for your internal gear-think routers, switches, servers-you need to lay out which IPs and subnets they use, plus their hostnames or device names. Basically, show your hand and make the IP landscape crystal clear.
- Demonstrate at least 50% efficient use for each allocation
- Show at least 80% overall efficiency across all allocations
- Provide reassignment details for 8+ contiguous IP address blocks via SWIP or RWhois
- Submit reassignment data in text or spreadsheet form for blocks under 8 IPs
- List CIDR ranges assigned to dynamic pools with service type, location, peak utilization, and customer count
- List web hosting IPs with at least one customer domain per IP
- List IPs/subnets assigned to internal infrastructure along with hostnames or device names
