ngx_dynamic_upstream doesn't check if ip address is valid when adding servers

[sunyq]

First of all, ngx_dynamic_upstream is really an awesome module!

During my test with ngx_dynamic_upstream I just found it doesn't check the validity of an IP address when I add a server for a zone. For example, if I add "10.1.1:8080" to the zone, the nginx process will be stuck, and I can't get response from nginx. I know this is not the correct way to use ngx_dynamic_upstream, but it would be much better to add an "IP address validity" check feature. Thanks!

I don't think that this module has to solve all problems.
