`CConnman::AlreadyConnectedToAddress()` searches the existent nodes by address or by address-and-port: ```cpp FindNode(static_cast<CNetAddr>(addr)) || FindNode(addr.ToStringAddrPort()) ``` but: * if there is a match by just the address, then the address-and-port search will not be evaluated and the whole condition will be `true` * if the there is no node with the same address, then the second search by address-and-port will not find a match either. The search by address-and-port is comparing against `CNode::m_addr_name` which could be a hostname, e.g. `"node.foobar.com:8333"`, but `addr.ToStringAddrPort()` is always going to be numeric.
