DNS zone data is stored in an application directory partition. A forest-wide partition named ForestDnsZones is used for the zone data. For each AD DS domain, a domain partition is created named DomainDnsZones. Typically, DNS implementations are used with a contiguous namespace.
Regarding this, where are DNS entries stored?
DNS Record. DNS records are stored in zone files and are used for translating domain names to IP addresses. They also contain other data, including the domain name’s name server and mail server information.
Similarly, what is forward lookup zone in Active Directory? A forward lookup zone is a DNS zone in which hostname to IP address relations are stored. When a computer asks the IP address of a specific hostname, the forward lookup zone is checked and the desired result is returned.
Similarly, you may ask, what is AD integrated zone in DNS?
The Active Directory Integrated zone stores its data in Active Directory and it does not need DNS zone files. It is in fact an authoritative primary zone and the data gets replicated to other domain controllers as part of Active Directory’s replication process.
How do I integrate a DNS server into Active Directory?
- Start the “DNS Management” MMC snap-in (Start – Programs – Administrative Tools – DNS Management)
- Expand the DNS server, expand the “Forward Lookup Zones”, select the domain, e.g. savilltech.com.
- Right click on the domain and select Properties from the context menu.
- Under Type click Change.

What happens when DNS TTL expires?
Time To Live, or TTL for short, is the sort of expiration date that is put on a DNS record. The TTL serves to tell the recursive server or local resolver how long it should keep said record in its cache. The longer the TTL, the longer the resolver holds that information in its cache.

What are the advantages of Active Directory integrated DNS?
The advantages of using AD-Integrated zone are as under: Replication : AD-Integrated zone is replicated using Active Directory replication. Because Active Directory can compress replication data between sites and replicates data securely, hence DNS replication also becomes fast, secure and efficient.
Is DNS required for Active Directory?
Active Directory must be supported by DNS in order to function properly, but the implementation of Active Directory Services does not require the installation of Microsoft DNS. A BIND DNS or other third-party DNS will fully support a Windows domain.

All domain-joined computers must use only internal DNS servers. If a domain-joined computer is configured to use an external server as an alternate DNS server, a temporary lack of connectivity to an internal DNS server will cause that machine to begin using the external server for resolution.
What is the command for reverse DNS lookup?
Nslookup is an MS-DOS utility that enables a user to look up the IP address of a domain or host on a network. The nslookup command can also perform a reverse lookup using an IP address to find the domain or host associated with that IP address.
