What is the importance of DNS?
DNS stands for Domain Name System. This system is arguably one of the most important aspects of the Internet. DNS ensures the Internet is not only user-friendly but also works smoothly, loading the content users ask for quickly and efficiently.
How does a policy-based DNS policy work?
If none of the server-level policies apply, the requested DNS zone comes into play. If the server is authoritative for this zone, the zone-level policies are checked and executed if the conditions are met. If the server is not authoritative, it will answer the request. Conditions within a policy are ANDed by default.
How does a DNS operator sign a TLD?
A DNS Operator that hosts DNS records signs them with DNSSEC keys. As a part of the process, they will generate a DS (Delegation Signer) record that must be provided to the parent zone (typically, a top-level domain (TLD)) to complete the “global chain of trust”.
What to do if DNS server restricts zone transfers?
Check the Zone Transfers tab of the zone properties in the DNS console. If the server restricts zone transfers to a list of servers, such as those listed on the Name Servers tab of the zone properties, make sure that the secondary server is on that list.
Where does validation take place in a DNS resolver?
Validation is performed by DNSSEC-validating DNS resolvers. It can be performed by a DNS resolver running at any point in your network, including a web browser, an instant messaging client or a mail server or client.
