|
|
Term
|
Definition
| A Domain Name System server that has the ability to process incoming queries from resolvers and send its own queries to other DNS servers on the internet, but which is not the authoritative source for any domain and hosts no resource records of its own. |

Term
| centralized DHCP infrastructure |
|
Definition
| In Dynamic Host Configuration Protocol,a deployment model in which all of the DHCP servers are all placed in a single location, such as a server closet or data center, and a DHCP relay agent is installed on each subnet, to enable the broadcast traffic on each subnet to reach the DHCP servers. |
|
|
Term
|
Definition
| A software component that receives the DHCP broadcast traffic on a subnet and then sends it on to particular DHCP servers on one or more other subnets. |
|
|
Term
| distributed DHCP infrastructure |
|
Definition
| In Dynamic Host Configuration Protocol, a deployment model in which at least one DHCP server is installed on each of the network's subnet. |
|
|
Term
|

|
Term
| full zone transfer (AXFR) |
|
Definition
| In the Domain Name System, a type of zone transfer in which the server hosting the primary zone copies the entirety of the primary zone so that their resource records are identical. |
|
|
Term
| fully qualified domain name (FQDN) |
|
Definition
| In the Domain Name System, the complete DNS name for a particular computers, consisting at minimum of a host name, second-level domain name, and a top-level domain name, written in that order and seperated by periods. |
|
|
Term
|
Definition
| In TCP/IP, the network interface inside a computer or other device on a network. |
|
|
Term
|
Definition
| In TCP/IP, a list of host names and their equivalent IP addresses, used for name resolution in the early days of the internet. |
|
|
Term
| incremental zone transfer (IXFR) |
|
Definition
| In the Domain Name System, a type of zone transfer in which the server hosting the primary zone copies only records needed to synchronize the primary master zone database file with the secondary zone. |
|
|
Term
|
Definition
| In the Domain Name System, a name resolution request in which the DNS server immediately responds with the best information it possesses at the time. |
|
|
Term
|
Definition
| In Dynamic Host Configuration Protocol, a method by which a DHCP server permanently assigns a specific IP address to a specific computer on the network. |
|
|
Term
|
Definition
| The process by which a Domain Name System server or other mechanism converts a host name into an IP address |
|
|
Term
|
Definition
| In the Domain Name System, a name resolution request in which the DNS server takes full responsibility for resolving the name. If the server has no information about the name, it sends referrals to other DNS server until it obtains the information it needs. |
|
|
Term
|
Definition
| The process by which one Domain Name System server sends a name resolution request to another tolerance. |
|
|
Term
|
Definition
| In the Domain Name System, a client program that generates DNS queries and sends and sends them to a DNS server for fulfillment. |
|
|
Term
|
Definition
| In the Domain Name System, a unit of information that can contain host names, IP addresses, and other data. |

|
Term
|
Definition
| In the Domain Name System, the process by which a server converts an IP address into a DNS name |
|
|
Term
|
Definition
| The highest-level DNS servers in the entire Domain Name System namespace. They maintain information about the top-level domains. |
|
|
Term
|
Definition
| In the Dynamic Host Configuration Protocol, a pool of IP addresses that DHCP servers assign to clients. |
|
|
Term
|
Definition
| In the Domain Name System, an administrative entity crated on a DNS server to represent a discrete portion of the DNS namespace. |
|
|
