How I Learned to Stop Worrying and Love the New Whois: RDAP


In the summer of 2015, you may have heard about a new service ARIN was rolling out called the Registration Data Access Protocol, or RDAP.

The waiting list for unmet requests has grown to over 200 organizations and the relative rate of incoming IPv4 free pool requests has decreased.

2015 Year in Review

ARIN IPv4 Free Pool Depletion

2015 was an exciting here at ARIN. While we are gearing up for 2016, I thought it would be interesting to recap this eventful year. I am fairly certain you heard that we ran out of IPv4 addresses in September.
