My turn for the newb question: I've got a traceroute with this IP in it thats close to the end of the trace. 103.206.16.46 Chasing down this IP to see who the ISP a friend is using, figured out the diff between ARIN and APNIC whois for IPs (..bit of a learning curve, not sure why there's not just one whois interface syntax). whois -h whois.apnic.net -m 103.206.16.0/21 shows only the upper /22 being registered with APNIC (if you do -m on .16.0/22, there's no entry). So it seems to me these Ips arent registered properly with APNIC (could it be cross-registered with another RIR? Well it's not with ARIN who'd be the local.) But I do see this block in global bgp tables so it wasnt like someone decided to use 10.10.10/24 or 1.2.3/24 in their routing infrastructure. They're actually announcing; sh ip bg 103.206.16.0 ends in a path with 394786 135022 looking up 394786 I see avetria networks. looking up 135022 I see nothing at ARIN. At APNIC I get as-block: AS134557 - AS135580 descr: APNIC ASN block remarks: These AS numbers are further assigned by APNIC remarks: to APNIC members and end-users in the APNIC region but nothing more specific. However, this does show up in radb as avetria networks as well. (and various geolocate DBs put it in Melbourn.au though i know it's in use in Kitchener ontario). So what's not matching up here? /kc -- Ken Chase - math@sizone.org Guelph Ontario
