Hi, I warn all my clients that PI (and any kind of their own) address space and/or AS is also a great responsibility. And they sure need a more qualified system administrator to rule it. If client asks for a help ("the Internet doesn't work") and rejects in help with doing some tests from its side - I say I can't help you in that case, goodbye. It is true as well for PI as for PA.

With PA, you can debug from *your* network - with customer's PI, you can't (normally) run probes (traceroute, ping) from *their* IP addresses - and if your PA works, but their PI is filtered, this makes it harder to debug. PI means that it is *not* your network administratively and technically. If customer have PI and AS - it is an independent part of Internet, and, in fact, not your just customer in usual terms. You don't go debug for example your downstream's and peer's networks as your, isn't it?

You need to distinguish between "customers with their own network block, their own AS number, BGP speaking routers, multiple upstreams, and local clue" and "customers that want PI space because they don't want to renumber when they change upstreams".

The latter sort will want *you* to announce their PI for them, and if there are any routing problems, yell at you because "the Internet doesn't work".

I have no issues with the former sort, especially when there is enough local clue present.

Furthermore, /24s tend to be damped more quickly and for longer times than /16... Again, why? ;)

Because flap dampening recommendations said so...
