bitcoin-cli getconnectioncount
Gives me an amount of 86 connections, my node has been running for a couple of months with 100% uptime.
educational purposesIs this a high number of connections? How many does your node have?
86 connections is an OK number. By default, bitcoind limits the connection count to 125 (
source). You can change that limit.
Mine:
$ bin/bitcoin/bin/bitcoin-cli getconnectioncount
117
I would also like to know if your node is visible on
https://bitnodes.earn.com/ or not, mine shows up there around 9/10 times I check.
Yes.
The same site also says:
The crawler maintained by Bitnodes connects from these IP addresses: 136.243.139.96, 136.243.139.120, 2a01:4f8:212:3b1f::2
Are these IP addresses usable with the
configuration?
Well, the 8333 port is open, but I think this must be a custom software that will connect to nodes to retrieve other hosts using the
getaddr call on other nodes, and doing this recursively, periodically checking if nodes it found were still alive. But maybe I'm wrong and this is a full node as well. Only them knows.
