The DNS Servers are hosted under 125.208.4[567].0/24 and none of our
peers do announce those routes to us.

The all, according to the looking glasses, seem to get those routes
announced from AS24406 CNNIC but do not redistribute them.


https://stat.ripe.net/125.208.46.1#tabId=at-a-glance

"125.208.46.0/24 is visible by 99% of 322 IPv4 RIS full peers."

Seems many get it.

Greets,

"Not Advertised to any peer" means that the Looking Glass itself is not 
re-distributing/Announcing it to another peer.

This is perfectly normal, we keep our internal RR split from the RR that does 
the route collection and then has a looking glass.

The Looking glass then has a clear "import only, export nothing" policy so yes 
this would also be "not advertised to any peer"

with your look up on the looking glass, you are looking at the view of this one 
BGP table, you're not seeing what the actual border routers are doing. This 
only tells you the presence of a route, not the actual redistribution

At least this is my understanding here ;)

Hi Benoit

Both DNS servers (NS.FMPRC.GOV.CN (125.208.45.1)) and NS3.FMPRC.GOV.CN 
(125.208.46.1) are slow, but working for me.

Hi List

A customer complained, he cannot reach the website of chinese embassy in
Switzerland. 

CH.CHINA-EMBASSY.ORG

The DNS Servers are hosted under 125.208.4[567].0/24 and none of our
peers do announce those routes to us.

The all, according to the looking glasses, seem to get those routes
announced from AS24406 CNNIC but do not redistribute them.

Do others also see this issue?

[swinog] Announcement of 'china government' routes 125.208.4[567].0/24 forbidden?

Hi List

A customer complained, he cannot reach the website of chinese embassy in
Switzerland. 

CH.CHINA-EMBASSY.ORG

The DNS Servers are hosted under 125.208.4[567].0/24 and none of our
peers do announce those routes to us.

The all, according to the looking glasses, seem to get those routes
announced from AS24406 CNNIC but do not redistribute them.

Do others also see this issue?

Mit freundlichen Grüssen
