"Tactical" /24 announcements

Mon Aug 9 16:03:31 UTC 2021

It's route table pollution if you ask me.. in today's world we have many 
IXPs and several tier-1 operators that support RPKI ROV, so when you 
have issued ROAs for the supernet of the IP space in question it'll 
already significantly reduce the effects of a BGP hijack.
