Philip,

How about if you post them to the list for now  and if
there are any problems I will let you know.

Thanks!

    Subject: routing stats
    Hi,
    
    Some of you might be aware that I've been posting stats from the Internet 
    routing table to the AsiaPacific Operators list (apops at lists.apnic.net) and 
    to the RIPE Routing WG (routing-wg at ripe.net). I've also been producing 
    stats covering ARIN's region, but so far have not posted them anywhere 
    apart from the APNIC web site.
    
    Basically I am examining the view of the Internet routing table as obtained 
    from NSPIXP2 in Tokyo, mostly for the benefit of the AP region's ISPs. At 
    the start of this year I extended it to cover the three RIR operating regions.
    
    Would it be interesting/appropriate if I posted the American summary to 
    this list? It is no more intrusive than the CIDR Report which Tony Bates 
    posts on a weekly basis to NANOG, and gives what I believe is a view which 
    is more focused on the region covered by ARIN. I've included a sample 
    output at the end of this e-mail, fyi.
    
    More information is displayed in graphical form on the APNIC web page, 
    specifically:

    best wishes!
