We can't always guarantee that the perfect solution to your specific problem will be waiting for you. How long entries are stored in the resolver cache depends on the Time to Live TTL value assigned to the record by the originating server.

These values are given as the number of seconds that a particular record can remain in the cache before it expires. These values are continually being counted down by the local computer. When the TTL value reaches zero, the record expires and is removed from the resolver cache. Occasionally, you'll find that the resolver cache needs to be cleared out to remove old entries and enable computers to check for updated DNS entries before the normal expiration and purging process takes place.

The system checks to see if the name is a FQDN, single label or multi label. This is determined by the dots within the name i. Note the terminating period on the FQDN and the lack of a terminating period on the multi label name.

Queries primary DNS server. If no response in two seconds it queries all remaining DNS servers. Resends queries to all servers at the four and eight second marks. Returns time outs for all queries after thirty seconds. Query is evaluated on whether it is 15 bytes or less. Query finally fails if no resolution has been achieved. Queries are re-issued with the connection specific DNS appended to the query.

Queries are then reissued devolving the parent DNS until only two labels are left. For a single label name the connection specific DNS is appended immediately and then it is submitted to the same resolution order as the FQDN. Tags: DNS , ipconfig.
