Description

Determines how long the Domain Name System (DNS) client waits for a response to each of the five attempts in the name resolution process. If the time specified for any attempt elapses before DNS receives a response, DNS repeats the query.

The value of this entry is an ordered list of five time limits (in seconds). The sixth value, which must be 0, indicates the end of the list. Each time limit is applied to the corresponding attempt in the name resolution process, in the following order:
