Hi,

since when does ftp://ftp.arin.net/info/asn.txt contain dotted
AS numbers? Where is the new formatting documented, asn.h ?

Since 32bit ASN's came out. People have been warned about this and it
has been discussed already a number of times on NANOG.

Also see RFC4893 :)

BTW, my parser scripts just convert them to 32bit numbers, as that is
what they are, nothing more, nothing less.

Greets,
