ipconfig's DNS features

ipconfig /displaydns

displays the contents of the DNS Resolver Cache (also known as the DNS cache). 

The DNS cache is a temporary DNS storage on your device holding already visited domain names.

Stuff you might see in there include some complicated microsoft.com related addresses under Record Name. Record type of 1 signifies an IP address (IPv4). Record type 2 (also known as a AAAA record) is an IPv6 address.  Record type 5 is an MX record (mail exchange). MX records show where mail for a domain should be routed to. Multiple MX records may exist for a single domain. Time to live is the time in seconds for the cache entry to expire.

These records represent the content of a DNS reply.
