The IXPs I've experienced explicitely prohibit announcment (i. e. routing) of their space nor announce it theirselves; so why spend another whole /15 as private address space? Obviously, there is no need for global routabillity, where is the need for global uniqueness and why can't this be solved differently (everyone has to cope with IPv4 scarceness, why can't IXPs)? As the pool of unallocated IPv4 addresses depletes, new IXPs will need to adopt new strategies, just like their customers. I'd support a movement to repurpose e. g. 198.18.0.0/15 for post-exhaustion IXP address space — if that's coordinated between the RIRs, it would help to support emerging IXPs for some time. Churning even more IPv4 space for local uses feels wrong: I oppose 2019-05. Regards, -kai
