Dear colleagues, does anybody have a hint for me where all those "unknown"/undocumented (usually 5digit) AS numbers are coming from ? Who is assigning them ? How can they be identified ? Sorry if this is a very stupid question, but I simply don't know where else to look for them (just an example, by "accident" I do know that AS11042 is used by LoralOrion): $ whois -h whois.ripe.net -a AS11042 [...] % No entries found for the selected source(s). [...] $ whois -h whois.ra.net -a AS11042 %% No entries found for the selected source(s). $ whois -h whois.arin.net AS11042 [...] No match for "AS11042". [...] Kind regards Christian --- ---------------------------------------------------------------------- --- --- Christian Panigl : Vienna University Computer Center - ACOnet --- --- VUCC - ACOnet - VIX : -------------------------------------------- --- --- Universitaetsstrasse 7 : Mail: Panigl@CC.UniVie.ac.at (CP8-RIPE) --- --- A-1010 Vienna / Austria : Tel: +43 1 4277-14032 (Fax: -9140) --- --- ---------------------------------------------------------------------- ---
