Select Test as BGP, choose any router and enter YOUR IP.

If you get the following error like me, that means Cogent is not reachable for you.

I think it is fine on BSNL too . both IPv6 & IPv4

 

[unnecessary]

@Lolita_Magnum BGP one is giving same result as yours.

@Zuke can't ping 66.250.250.89 because of request timed out.

 

[Lolita_Magnum]

66.250.250.89 is a pingable Cogent IP and will be unreachable for you until this is fixed.

My OneB connection when checked using cogent looking glass BGP test

BSNL is good as it has TATA, Bharti Airtel, Vodafone, Reliance Jio as upstream.

 

[sloj]

@TheNuttyNet What was your network prefix when you checked that?

 

[TheNuttyNet]

@sloj 203.xyz.pq.abc something


Rn my ip is -103.38.69.xyz and i can successfully get result using cogent looking glass US server

 

[sloj]

The 103.38.69.0/24 has Tata and Airtel upstream and route to Cogent goes through Airtel. I guess the previous one had no route to Cogent and was a Tata only upstream.
