The zone data is stored in the Active Directory database rather than in a zone file.
Active Directory integrated zone
Works at the Internet layer and is responsible for mapping IP addresses to MAC addresses assigned to the network interface adapter. These can be either dynamic or static entries. Dynamic entries are stored in the ARP cache for two or 10 minutes. Static entries stay in the cache until the computer is restarted.
Address Resolution Protocol (ARP)
This is the 32-bit number of the router on the local network, which is used to communicate with hosts outside of the local subnet.
default gateway
Used for two essential tasks: host name to IP address resolution and for the location of network services, such as domain controllers that provide user authentication.
Domain Name System (DNS)
Used to centralize the administration of IP addresses and various options, and eliminate the administrative overhead of statically assigning the information to each network host.
Dynamic Host Configuration Protocol (DHCP)
Used to perform the standard host name to IP address forward lookup queries.
forward lookup zone
Describes the location of the host in relation to the DNS namespace. For example a computer named "webserver" in the marketing domain of would have the FQDN of
fully qualified domain name (FQDN)
Any computer that is a member of a specific DNS domain within the network structure.
Operates at the network layer and is used to exchange status and error information between two hosts.
Internet Control Message Protocol (ICMP)
Operates at the network layer and is used to manage network and host information when multicasting is used.
Internet Group Management Protocol (IGMP)
The Internet layer protocol responsible for the addressing and routing of packets so that they are delivered to the correct host on the local network or across routers to a host on another subnet.
Internet Protocol (IP)
The 32-bit number that uniquely identifies a host on a TCP/IP network.
IP address
A command used to verify the addressing parameters assigned to a computer.
The ipconfig command plus the all parameter is used to produce a full display of assigned parameters.
If the DNS server cannot resolve a name, it gives the requestor a pointer to another DNS server that is authoritative for the next level of the FQDN supplied.
iterative query
The sending of a message to multiple clients, or a group of clients.
A command that combines the functions of the ping and tracert commands. The ________ command checks network connectivity by sending echo request messages to each router between a source and destination host and then computing the result based on packets returned from each router.
A command used to test for connectivity between hosts on the network by sending ICMP packets to a remote computer and listening for an echo reply from the remote host.
A command that specifies the return of a complete and full answer to the query, not a pointer to another DNS server.
recursive query
A specific type of zone that performs reverse IP address to host name resolution queries.
reverse lookup zone
A range of IP addresses configured on a DHCP server that can be handed out to network clients.
The DNS zone file is stored as a regular read/write text file in the %systemroot%\system32\dns folder.
standard primary zone
A read-only zone file is copied from a configured standard primary zone.
standard secondary zone
The 32-bit number that identifies the network to which a TCP/IP host belongs
subnet mask
A grouping of scopes created for multiple subnets on a physical network.
A command used to determine the route taken to a destination by sending ICMP echo packets with varying time-to-live (TTL) values to the destination.
Operates at the transport layer and is responsible for the reliable transmission of data on a TCP/IP network.
Transmission Control Protocol (TCP)
Consists of a suite of protocols and utilities that are used for network communication and troubleshooting on local networks and the Internet.
Transmission Control Protocol/Internet Protocol (TCP/IP)
A connectionless protocol that functions at the transport layer and provides no guarantee of delivery.
User Datagram Protocol (UDP)
A Windows 2000 service that is used to resolve NetBIOS names to IP addresses.
Windows Internet Name Service (WINS)
A command used on Windows 9x machines to display the TCP/IP configuration settings.
A DNS configuration file that holds all of the resource records for the domain, such as computer name records, mail exchanger records, and service records.
zone file
The copying of the DNS database information between the primary and secondary zones.
zone transfer
