no-ip still lives, they just lost 22 of their cool IP's and were left with shit. Supposedly the cool IPs supposed to work, and its been verified sometimes they do.. but most the time they dont. This is what NoIP said about it.
"We have been in contact with Microsoft today. They claim that their intent is to only filter out the known bad hostnames in each seized domain, while continuing to allow the good hostnames to resolve. However, this is not happening. Apparently, the Microsoft infrastructure is not able to handle the billions of queries from our customers. Millions of innocent users are experiencing outages to their services because of Microsoft’s attempt to remediate hostnames associated with a few bad actors."
