DNS (Domain Name System) is a hierarchical decentralized naming system used to translate domain names into IP addresses. It enables users to access websites and services using user-friendly domain names instead of remembering numeric IP addresses.

A DNS query is a request made by a client to a DNS server to resolve a domain name into an IP address.

In DNS, a zone refers to a portion of the DNS namespace for which a particular DNS server is authoritative. It contains records that define the mapping between domain names and IP addresses.

DNS records are entries within a DNS zone that contain information about a specific resource. The most commonly used DNS record types include A records (maps a domain name to an IPv4 address), AAAA records (maps a domain name to an IPv6 address), CNAME records (creates an alias for a domain name), MX records (specifies the mail server for a domain), and TXT records (stores arbitrary text-based data).

A stub zone is a type of DNS zone that contains only a minimal set of records necessary to identify the authoritative DNS servers for a particular zone. It is used to delegate DNS resolution for a specific domain to another DNS server.

PTR (Pointer) records are used in reverse DNS lookups to map an IP address to a domain name. They are commonly used to verify the identity of email servers and establish a reverse mapping for IP addresses.

Point records are not a specific term in DNS. It may be a typographical error, but if you are referring to an A record (address record), it is a type of DNS record that maps a domain name to an IPv4 address.

The number of DNS records that can be created manually in a DNS server depends on the specific DNS server software being used and the limitations set by the administrator. In general, there is no fixed limit on the number of records that can be created, but practical considerations such as server resources and performance may impose limitations.

A file server is a computer or storage device that is dedicated to storing and sharing files over a network. It allows multiple users to access and manage files centrally.

Quota policy refers to the set of rules or limits imposed on file server storage space usage. It determines how much storage space a user or a group of users can consume on the file server. Quota policies are often used to control and allocate storage resources efficiently.

DHCP (Dynamic Host Configuration Protocol) is a network protocol that automatically assigns IP addresses and other network configuration settings to devices on a network. It eliminates the need for manual configuration of IP addresses.

A DHCP scope is a range of IP addresses that a DHCP server can assign to devices on a network. It also includes other configuration parameters such as subnet mask, default gateway, and DNS server addresses.

A subnet is a logical subdivision of an IP network. It allows a large network to be divided into smaller, more manageable segments. Subnetting is the process of dividing an IP network into subnets.

IP ranges refer to a range of IP addresses within a given subnet or network. An IP range specifies the starting and ending IP addresses that define the range.

Protocol refers to a set of rules and conventions that govern how data is transmitted and communicated between devices on a network. Examples of protocols include TCP/IP, HTTP, FTP, and DNS.

The OSI (Open Systems Interconnection) model is a conceptual framework that standardizes the functions of a communication system into seven distinct layers. These layers include the Physical layer, Data Link layer, Network layer, Transport layer, Session layer, Presentation layer, and Application layer. The OSI model helps in understanding how different network protocols and technologies interact with each other.

Topology refers to the physical or logical arrangement of devices, nodes, and connections in a network. It describes the layout and structure of the network and can incl
