As the security incident manager for this particular vulnerability notification, I'd like to say a little extra, beyond our official vulnerability disclosure (https://kb.isc.org/article/AA-01272) about this critical defect in BIND. Many of our bugs are limited in scope or affect only users having

http://www.vip.icann.org/DS? The http:// and /DS wouldn't be part of DNS name itself so you can't dig for that. You'd have to point a browser (or command line tool like wget or curl) to get that web page. The vip IS part of the DNS name. Did you try "dig www.vip.icann.org"? It works for m

Since the OP says he's not in Production yet I'd strongly advise moving on to CentOS 7 for multiple reasons. I has a new base version of BIND and also has a 3.x kernel. However, there is a learning curve because it also uses systemd rather than Sys V init. The way bind-chroot runs is signifi
