DNSSEC zone walking is a technique used to extract information from DNSSEC-signed zones by iterating over the DNS tree. DNS cache snooping is a technique used to obtain information about a DNS server's cache by sending queries for non-existent domain names. DNS enumeration is a technique used to gather information about a target network by querying DNS servers for information about the network's hosts and services.
