Hi, laplasz. No, you must be mistaken, this ip 20.52.42.128 does not belong to adastat.net

laplasz · 17 April 2021 06:55

Sorry - I made a wrong query on ledger log - now I modified the topic to the right pool name, thanks for clarification!

joseiadicicco · 29 April 2021 12:41

I have the same issue with the other relay IP of the same “Pool” or whatever it is:

laplasz · 29 April 2021 12:49

thanks! this should be addressed somehow… will come back if I find out something…
yes - it is the same pool - I searched the IP address in the ledger state file:

cardano-cli query ledger-state --mainnet > ledger-state.json
grep -B30 40.121.22.88 ledger-state.json

The additional connections still increasing, now I have 63 Peers In connections from the same IP address (40.121.22.88) and different port numbers. I would like to know what are they trying to do? This IP address corresponds to Microsoft Azzure Cloud Services, so, they are creating multiple relays on the same IP, with different Port numbers. I would like to contact the SPO and let him know its a wrong configuration for the network. 63 Relays!
