and see if announcing an upstream /48 works. You can use e.g. ripe
atlas or other measurement networks to test connectivity paths while
upstream mitigation is in place, both with a /48 IRRDB entry for the
announcement in question, and without. This should give you a clear
idea about whether using individual /48s is worth the effort (I suspect
the answer is probably not).<br><br>Nick<br><br></div></body></html>
