AS 1717 and 5511 ?

While doing some analyzing of traffic, AS paths, etc. I saw very often AS 1717 and 5511. ARIN doesn't show anything for 1717 in the whois database. 5511 shows as being in a block to RIPE. Ripe shows nothing for 5511 or 1717. The address blocks seems to be all routed to Renater.fr, who is also listed as AS1717-MNT. Wonder how many more AS numbers are out there not listed.... -- Regards, Ulf. --------------------------------------------------------------------- Ulf Zimmermann, 1525 Pacific Ave., Alameda, CA-94501, #: 510-769-2936 Alameda Networks, Inc. | http://www.Alameda.net | Fax#: 510-521-5073
