| Question | Answer |
|---|---|
| Domain Name System (DNS) | A system for naming resources on TCP/IP networks. Using names instead of IP addresses. |
| Domain Name | A name assigned to a hierarchical partition on the DNS namespace. |
| Fully Qualified Domain Name (FQDN) | The name generated by concatenating a hostname with a domain name. |
| Hostname | A single name used to identify a computer (host). |
| LMHosts | A file that associates IP addresses to NetBIOS names. |
| Resource Record | An entry added to zone files. There are a number of resource record types, and each has a specific purpose. |
| WINS (Windows Internet Naming Service) | A WINS server is a Microsoft implementation of a NetBIOS name server |
| Zone file | The configuration files used by DNS servers. These text files are used to configure DNS servers. |
| Start of Authority (SOA) | The SOA resource record designates the authoritative name server for the zone |
| Name Server (NS) | The NS resource record designates a name server for the zone. A zone may have several name servers but only one SOA record for the authoritative name server. |
| Address (A) | The A resource record maps a DNS name to an IP Address |
| Pointer (PTR) | The PTR resource record maps an IP address to a DNS name. Reverse lookup |
| Canonical Name (CNAME) | A CNAME resource record maps an alias to the actual hostname represented by an A record |
| NSLookup | A DNS command line utility that enables you to query DNS servers an view information such as resource records. It is used to troubleshoot DNS. |
| DDNS (Dynamic DNS) | Used in conjunction with DHCP to obtain the name from the IP address when while using DHCP (Dynamic Host Configuration Protocol) to obtain IP addresses automatically. |
| APIPA Automatic Private Addressing | A Link Local Addressing technique used on some MS systems. Assigns IP address in the 169.254.0.0 range when DHCP server cannot be reached. |
| BOOTP | Protocol used primarily to assign addresses to diskless clients. |
| DHCP Dynamic Host Configuration Protocol | A protocol that provides dynamic assignment of IP addresses, subnet masks, default gateways, DNS server addresses, and more. |
| DHCP client | A computer that contains TCP/IP software and is not manually configured with TCP/IP parameters. |
| DHCP server | A computer that is capable of configuring DHCP client computers with an IP address, a subnet mask, and other TCP/IP configuration parameters. |
| DNS Service DISCOVERY | A means for clients to learn about services on a zero configuration network. |
| Link Local Addressing | A technique for zero configuration IP address assignment. |
| Multicast DNS | DNS Name resolution without a server or a preconfigured hosts file. |
| Zeroconfig | A collection of protocols designed to deliver TCP/IP services with zero configuration. |
| NAT Network Address Translation | A secure method of using a private addressing scheme internally that is translated to a public IP address to the Internet. |
| 10.0.0.0 - 10.255.255.255 | Class A range of private addresses. These cannot be routed on the Internet. |
| 172.16.0.0 - 172.31.255.255 | Class B range of private addresses. These cannot be routed on the Internet. |
| 192.168.0.0 - 192.168.255.255 | Class C range of private addresses. These cannot be routed on the Internet. |
| 169.254.0.0 - 169.254.255.255 | Address range used by APIPA if a DHCP server is not available. Also called Link Local Addressing. |
