DNS resolver now counts how many sendto operations are successful during one DNS server attempt cycle (attempting to contact DNS servers from 0 to last index, including stack specific ones). If all socket sendto operations fail, DNS resolution is aborted. If one or more are successful, DNS resolution is continued until total network attempts count is reached or all sendto operations fails during a cycle.
