 BIO_set_accept_port() uses the string B<name> to set the accept
 port. The port is represented as a string of the form "host:port",
 where "host" is the interface to use and "port" is the port.
-The host can be "*" which is interpreted as meaning
-any interface; "port" has the same syntax
-as the port specified in BIO_set_conn_port() for connect BIOs,
-that is it can be a numerical port string or a string to lookup
-using getservbyname() and a string table.
+The host can be "*" or empty which is interpreted as meaning
+any interface.  If the host is a IPv6 address, it has to be
+enclosed in brackets, for example "[::1]:https".  "port" has the
+same syntax as the port specified in BIO_set_conn_port() for
+connect BIOs, that is it can be a numerical port string or a
+string to lookup using getservbyname() and a string table.
 
 BIO_new_accept() combines BIO_new() and BIO_set_accept_port() into
 a single call: that is it creates a new accept BIO with port
