I am a bit confused with how ARIN assignments work. I've never had to deal with it before, so i'm looking for some clarification.
I've read in ARIN's policies that to end-users, they will only assign a /20, a /22 to dual-homed customers. However, I've heard people mention getting smaller blocks from ARIN, like /24. How is this possible? Or is it even possible?
We're currently using 4 discontiguous /28 networks from our ISP, I'd like to get an ASN, purchase an address space and become dual-homed, but I'm not certain we can meet the utilization requirements for a /22, but we definately could for a /24.
Here is the regulation:
4.3.3. Utilization rate
Utilization rate of address space is a key factor in justifying a new assignment of IP address space. Requesters must show exactly how previous address assignments have been utilized and must provide appropriate details to verify their one-year growth projection. The basic criteria that must be met are:
A 25% immediate utilization rate, and
A 50% utilization rate within one year.
A greater utilization rate may be required based on individual network requirements. Please refer to RFC 2050 for more information on utilization guidelines.
Any help would be greatly appreciated.
