(secondary) zones. This idea is about how DNS information is handled and distributed inside a network, and it has important consequences for network architecture, corporate security, and technology management. Let's look at the master zone vs. slave zone. The master zone is responsible for maintaining the original, authoritative copies of DNS records. It contains the definitive version of the DNS database for a specific domain. DNS records are frequently changed or updated on the master server. The slavery zone serves as a backup and helps to distribute the DNS load, and it cannot be updated directly; instead, periodic zone transfers from the master server are required. Then there is the slave zone, which contains the authoritative DNS data, so security precautions must be taken. Also, the slavery zone reduces risk by not directly handling updates; instead, it relies on the master for authoritative data. 2nd Response 4-1 Discussion: Static vs Dynamic Russell Hawkins Setting static DNS Requires a lot of effort on the part of the network administrator. They have to update any changes manually and add in new locations as needed. However, it is much more secure. It is much more difficult for an attacker to sneak in if a human is monitoring and having to manually update the DNS records. Dynamic DNS requires much less effort to set up as the server makes changes and adds locations as needed. the down side to this is that it is easier for an attacker to create a false record. for "Man in the middle attacks" or "DNS cache poisoning" to name a couple. So what do we do? At my job we use Dynamic DNS. We use several programs to manage and monitor the DNS records looking for threats.

Or Provide additional considerations, advantages, or implications related to the original post. A Domain Name System (DNS) "zone" is a section of the DNS namespace governed by an entity or organization. A DNS server manages it as a domain or component of one. Zones spread DNS database management and domain authority, and key zone ideas include resource record types and zone transfers.
