-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear colleagues, In a cooperation between the RIPE NCC and ARIN we investigate the visibility/reachability of longer-than-/24 prefixes out of ARIN's 23.128/10 IPv4 address block. This part of ARIN policy (https://www.arin.net/policy/nrpm.html#four10) elicited much discussion on NANOG earlier this year, so we decided to try and measure the current state of the network with regards to longer-than-/24 IPv4 prefixes. We've now published a RIPE Labs article with initial analysis results: https://labs.ripe.net/Members/emileaben/propagation-of-longer-than-24-ipv4-p... Spoiler: the longer-than-/24 prefixes are not very visible/reachable. Having route-objects improves visibility/reachability, but only a little bit. cheers, Emile Aben RIPE NCC -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAEBAgAGBQJUMqgKAAoJEKxthF6wloMO9LUQAITnqRgmI0G7yD7Vv7E30wpu W2YwXV6nP3ssq7XDE/ByqmXzDycS9Iu3/h+IK9Th5KqeCJIfGsyIDGvD1P4QCswd vyTA0a6iND03cX1JbuuA6mQZyf7oeIsFeCUzxjTBBTU0K2O62ngrnr74K6LCFNx9 2k4gSyyn1BJ4FQpgXgRnaADrcKR9pvYXa92HRCXZwXl7hBsbo213u79CNc8iF6nH einYXqifNzxjoNtUqHKDPFX93t5nHSUGJBqV2Xe/Lr89aGSGkXdlGZqd1GhFdaPf O0gryNJWg2r3maM0THte/UYIzFKaVS71f5eZj+blj1eb9mIxLcVPtIdh8rB7JJ8r Pyi3yOjBdusntGY3dfsG4pYV80og2yn8AIVQde0hBEoreESjqGzMv74ZO7avXtZ6 K3c48uS/sL49EXafDgiinJ+9YblqCd4+cw0YockbCl5WFSZGRzth1R1J7UESgVH6 gk0yO9BzmHcuNLcxJVfRJJV4NkEJ+sVAuFwFWmushPjQWm1PGLDCVBhRvynOxvOK eqff9Rs0SkQpJ9gN05HnaWcb87gjjTFKWxZ8l2xbZo4JkAgRSvMLkrthviSvN2PX 7DhGlC+hlq4mpR/y1YwiEF4oMFkH9feni4P0lFfbLNR2I72MyAv0lIu9hawIUpwn ryDIUKXZOvPifOAs/5PA =vaXm -----END PGP SIGNATURE-----
