None of the numbers I included should be seen in the global tables,  
that is why I included them. However, these bogons are basically  
always there (not the same set, but something), and
I as far as I can tell they are fairly benign. The "private"
ASN I have tracked down in the past have all been apparently
innocent mistakes.

If someone wanted to phish from an AS,
there are lots of others that would not be so obvious. Right now, for  
example,
I see 19 ASN from Afrnic blocks with no WHOIS info at all, which  
worries me rather more.
