Have you heard of RPZ? The TL;DR on RPZ is that the concept of things like Spamhaus RBL blacklisting to quickly resolve SPAM is going to start expanding into DNS so it is domain (or potentially TLD) based and not protocol-specific
Paul Vixie from Farsight will be speaking at MERGE about RPZ - many of you have the privilege of knowing him and his many contributions to the stability and security of the Internet
This is something that a network administrator can institute at its perimeter nameservers / firewall, but that dominion can be a nation or a large ISP just as easily as a company.
RPZ is worth some awareness within UASG as it may impact domain names from resolving everywhere immediately that are first activating because RPZ intentionally creates a delay (I am oversimplifying this)
The delay is involved intentionally to counter fast-flux or fluid-instant registrations often seen in command and control networks, and there are some exceptions and tuning that can happen.
