Dns not updating from dhcp server 2016
Someone might still be able to get a certificate for a different, not-so-well-known, certificate authority named CA2.
Then, the entity hosting the fake might be able to corrupt the DNS cache of a client or server to point their fake site.
This prevents a form of man-in-the-middle attack where someone is able to corrupt a DNS cache and point a DNS name to their own IP address.
For instance, imagine you host a secure website that uses SSL at using a certificate from a well-known authority named CA1.
Without RRL, your DNS servers might respond to all the requests, flooding the third computer.
When you use RRL, you can configure the following settings: You can use DANE support (RFC 63) to specify to your DNS clients what CA they should expect certificates to be issued from for domains names hosted in your DNS server.
For more information, see the DNS Policy Scenario Guide.
The DHCP console provides statistics concerning IPv4 and IPv6 address availability and usage.
By doing this, you can prevent someone from sending a Denial of Service (Dos) attack using your DNS servers.
For instance, a bot net can send requests to your DNS server using the IP address of a third computer as the requestor.
The following items provide more detail about these capabilities.
You can also use DNS policies for Active Directory integrated DNS zones.
