A network tech came to visit with me today,
and at some point I mentioned offhandedly:
This was configured as 192.168.100.15 because that's
the /24 subnet that we were using back in December,
but we've since bought a real subnet from ARIN
and moved to that--see, this one here...
His eyes widened a bit and he said:
You bought a /24 from ARIN?
a /21, actually.
His eyes widened a lot and he inquired:
You were able to buy a /21 from ARIN in 2015!?
OMG. How did you manage THAT!?
Apparently people are endlessly impressed by this
(this is something like the eleventh such reaction I've got).
