1410	default_server with no IP specified for multiple IP servers	gmchain@…		"I've encountered a problem whilst configuring a system with multiple IP addresses: default_server directive should be specified for every IP-address used for web connections, no matter if there should be only one default server in the configuration. So, in case of adding a new IP I should alter the configuration to add that IP.

I think it should be more transparent if nginx would look for default servers for IP:port pair first, after that for other suitable default servers and only after that use a first server in list of configured servers.
