+# Initial connection
+
+When a client connect to a server, the server might output:
+```
+↙️ :server NOTICE * :Checking Ident
+↙️ :server NOTICE * :Looking up your hostname...
+↙️ :server NOTICE * :Couldn't find your hostname
+↙️ :server NOTICE * :No Ident response
+```
+What the server does is:
+1. Check the client's hostname (domain) via an rDNS lookup of the IP address.
+2. Try to connect to the client's [Ident server](https://en.wikipedia.org/wiki/Ident_protocol) (if it has one)
