Your DNS May Be EOL
So, I’ve gotten 2 separate notes from 2 separate vendors over the last couple of days proclaiming similar things. Recently, ISC has declared several older versions of BIND “End of Life“. These older versions are no longer supported and may or may not have security issues. But, if your boss gets one of these, you can be sure that he/she will forward it on to the technical people out on the pointy end of the stick to answer for. I hope you don’t even have to think twice, you shouldn’t be running this stuff anymore.
