Hi, I know of some enterprise IT equipment that does this. It was reserved space at the time it was picked. It does not leak from the box, but every once in a while one of these IPs show up in a customer visible log, and causes confusion. In ways it is better then rfc 1918 space as it has less chance of conflicting with a management network. Harry On December 17, 2017 3:42:48 PM MST, Richard <rgolodner () infratection com> wrote:

I just heard ofthis happening with a large ISP and never really thought about it until now.RobertIt is more common than you would think. Why use public IP's when you can have many rfc1918 options. Always amazes me after the initial confusion. Richard
