MINOR: standard: Disable ip resolution during the runtime

The function str2net runs DNS resolution if valid ip cannot be parsed.
The DNS function used is the standard function of the libc and it
performs asynchronous request.

The asynchronous request is not compatible with the haproxy
archictecture.

str2net() is used during the runtime throught the "socket".

This patch remove the DNS resolution during the runtime.
