What is reverse lookup zone and forward lookup zone?
There are two main categories of lookup zones: forward lookup zones and reverse lookup zones. Forward lookup zones are used to map a host name to an IP address. Reverse lookup zones are used to map IP addresses to host names.
What are the 3 types of reverse lookup zones?
Reverse Lookup Zones. As mentioned earlier, a reverse lookup zone is an authoritative DNS zone that is used primarily to resolve IP addresses to network resource names. This zone type can be primary, secondary, or Active Directory—integrated.
What is the zone in my forward lookup zone?
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 host name, the forward lookup zone is checked and the desired result is returned. In Order to Create a New Forward Lookup Zone: You have to start the DNS snap-in.
How do you create a forward and reverse lookup zone?
Configure the forward lookup zone Click Start, point to Administrative Tools, and then click DNS. In the console tree, under DNS, click Host name (where Host name is the host name of the DNS server). In the console tree, click Forward Lookup Zones. Right-click Forward Lookup Zones, and then click New Zone.
What is a record and MX record?
The MX-record contains the host name of the computer(s) that handle the emails for a domain and a prioritization code. Emails are routed through to the IP address which is set in the A-record of the host. The A-record (or address-record) determines which IP address belongs to a domain name.
What is the difference between a forward lookup zone and a reverse lookup select two?
What is the difference between a forward lookup zone and a reverse lookup? -A forward lookup finds the IP address for a given host name. -A reverse lookup finds the host name from the given IP address.
How do you do a reverse lookup zone?

What is SOA record in DNS?
The DNS ‘start of authority’ (SOA) record stores important information about a domain or zone such as the email address of the administrator, when the domain was last updated, and how long the server should wait between refreshes. All DNS zones need an SOA record in order to conform to IETF standards.
What are reverse lookup zones used for?
A Reverse Lookup Zone contains all the records of IP addresses to their domain names. It would be too easy to define a reverse lookup as the opposite of forward, but it is true. A reverse lookup zone is used any time you want to convert an IP address to a name.
What is forward zone file?
Forward lookup zones host domains and are, essentially, flat databases with records that are used to translate hostnames into IP addresses. Each zone can be used as a management boundary for, as an example, a single domain or a domain and all of its child domains.
What is TTL in SOA record?
SOA TTL (seconds) – The time-to-live (TTL) of the zone’s start of authority (SOA) record. This value indicates the amount of time resolvers cache the SOA. Default is 3600 seconds (i.e., 1 hour). Refresh (seconds) – The amount of time between each attempt by the secondary DNS servers to refresh the primary zone file.
What are DNS zones?
A DNS zone is a portion of the DNS namespace that is managed by a specific organization or administrator. A DNS zone is an administrative space which allows for more granular control of DNS components, such as authoritative nameservers. The domain name space is a hierarchical tree, with the DNS root domain at the top.
