[AusNOG] 103.0.0.0/8 (Asia Pacific Network Information Centre)

Mon Sep 10 22:45:27 EST 2018

Just two things to clarify

BGP.HE.NET data is not the HE networks production data it is gathered from several public sources and not a reflection of bgp @ AS6939

https://bgp.he.net/ip/103.0.0.0

AS6939 BGP best path can be found @ https://lg.he.net/

Thanks

HE’s tool might be the problem…

route-views>sh bgp ipv4 unicast 103.0.0.0/8
% Network not in table

Even though it’s a covering prefix, not good to see AS13030 advertising it; more specifics should however limit the damage.

I count 44  * /8 advertised by AS13030

Strange….

Hi Matthew,

What you're seeing is a description of the block that attributes it to APNIC. But in fact it's being originated by AS13030, Init7. https://bgp.he.net/AS13030

RIPE confirms they see it too:

Arvo Guys,

Has anyone else noticed that APNIC appears to be advertising the entire 103.0.0.0/8<http://103.0.0.0/8> range for some reason? I have seen this a few times by international carriers.

Is anyone else seeing the same issue on bgp.he.net<http://bgp.he.net> for their ranges.

See screenshot
