Ip justification

In assigning IPv4 and IPv6 address space to Internet subscribers, ISPs take guidance from assignment policies and procedures set forth by ARIN (American Registry for Internet Numbers) Number Resource Policy Manual, RFC 2050, and RFC 3177. IP address space is assigned based on utilization efficiency guidelines as defined by ARIN Number Resource Policy Manual, RFC 2050, and RFC 3177.
