Re: Cogent move without renumbering (was: Cogent/Level 3 depeering)

in a pay-me-now-or-pay-me-later scenario, you have to pick "now" vs. "later".
(it's a pity that the internet, for all its power, cannot alter that rule.)

It should be noted that if one opts for 'later', you can do quick and dirty games with NAT. Do not renumber, change providers and put a NAT between yourself and your provider. This will continue to work until such time as your original PA space is reassigned and then you will not be able to reach the new assignee. This allows for quick moves, but creates the mortgage of an eventual renumbering. Folks who take this approach are likely to renumber into RFC 1918 space.

Before you break out the blowtorches, I'm *not* claiming that this a good way of doing things. It's a hack. It's expedient. ;-)
