The last time I guessed at the color code, as in, just use 568-B like I always do, it didn't work. Uh oh, maybe 568A, no, some homegrown code and I have no clue where the other end was. So, after further review, I just matched the code from the end I cut off and it worked. What was it? Who cares! The site was 2 hours away and I had 12 AP's to reprogram.
Of course, the reason I had to do that is because the owner just picked IP's out of a hat as 184.101.176.1 or some such random illegal IP addresses. When I was done, I had 12 numbers 10.0.0.1 to 10.0.11.1. Worked like a charm.
