Hello, I am new (and sorry in advance for my language I am French).
I would like to know how we connect to the blockchain, to the network, when there is no ip?
Indeed we all use bitcoin core (for bitcoin) to connect and retrieve information and update.
However the source code of bitcoin core (I have never read it) does not redirect us to an ip, but people still manage to find themselves, without ever saving the ip.
How can people know or find the information, when the source code of the software does not have ip, they do not know address (ip) which has the information?
Knowing that the ip is the basis of the connection ...
