No, this is not a common practice, although a few of the 350 exchanges out
there may do so.

Yes, some ISPs verify that their peers' announcements and IRR registered
prefixes match.  The vast majority do not.

Absolutely not, as that intrudes upon the terms of the commercial
relationship between the individual members of the exchange.

Besides which, the IX has no way of observing or enforcing any such policy
without violating the privacy of the members.  There is, of course, no
reason to believe that members will advertize the same prefixes to a
looking-glass, even a private and mandatory one, that they advertize
amongst themselves.  This is a rat's nest that there's no motive for
jumping into.

Actually, this trend has been in the opposite direction, decreasing
interest in IRRs, for the past six or eight years, to my observation.
Perhaps others believe otherwise.
