<p class="MsoNormal">To be upfront, we use a non-RFC1918 for our internal network - something unrouted, that hopefully stays that way... but even if it doesn't, it isn't a huge drama to renumber or just not talk to them. An ever growing amount of our traffic

I'm reminded of a past job interview episode here.<br>
<br>
When a person applying for a System Administration role was asked the<br>
question "Can you give me an example of a private IP address?", the<br>
answer was as follows.<br>
<br>
"1 dot 1 dot 1 dot...(pause seeking cues of approval from myself and the<br>
other interviewer) 2?"<br>
<br>
Interestingly, as soon as we asked for an example of an RFC1918 address,<br>
we were given very correct details. Practice and best practice don't<br>
always align it would seem!<br>
