DNS A Record

An A record in DNS is the fundamental record type used to assign an IP address to a DNS name. Devices on their own do not understand how to communicate with human readable names, and so the DNS server acts as a phone book to make sure we’re “calling” the right number.

DNS

DNS Records

Domain Name System (DNS) Records are contained within DNS zones. They provide the information about a particular domain to ease communication and often help with security.

IP Address

An Internet Protocol address, or IP address, is a string of characters that are used to identify a device on a layer 3 network.

DNS

What is DNS?

Domain Name System (DNS) is a protocol that allows us to use human readable names to communicate over networks, rather than having to manage and memorize IP addresses.

What is a top-level domain?

A top-level domain (TLD) is the right-most part of a domain name. Some of the most common TLDs are .com, .net., and .gov.

Generic Top-Level Domains

Generic Top-Level Domains or gTLDs are likely the most familiar to people. These are the domains that end in three-letter domains like .com, .net, and .gov.

DNS

What is a TXT Record?

The “TXT” in DNS TXT Record stands for text. This record allows admins to add any kind of text to their DNS (domain name system) zones, like human readable notes for example.

DNS

DNS SOA Record

DNS SOA Record stands forDomain Name System (DNS) Start of Authority (SOA) Record and contains administrative information about a domain or zone.

DNS

DNS Server Types

DNS (Domain Name System) is a hierarchical system in which there are different types of DNS servers at each level. These types are Root DNS servers, Top-Level Domain Servers, Authoritative servers and DNS Resolvers.

DNS

DNS Root Sever

A DNS (Domain Name System) Root Server, or root name server, is at the very highest level of the DNS hierarchy and essentially manages domain names for the entire Internet.

DNS

DNS PTR Record

A PTR record stands for “pointer” record, and is commonly also called a “pointer record.”

DNS MX Record

The MX resource record in DNS refers to a mail exchange record.

DNS

DNS DKIM Record

A DomainKeys Identified Mail (DKIM) record is a special type of DNS TXT record which helps authenticate emails.

DNS

DNS CNAME Record

In DNS, CNAME is short for Canonical Name. A CNAME creates an alias for other DNS names.

Network Security (DDoS)

Country Code Top-Level Domain

A country code top-level domain (ccTLD) is a TLD that represents a particular country. The top-level domain is the highest part of the domain hierarchy run by ICANN.

DHCP

What is DHCP?

DHCP is a network protocol used in IP networks that automatically assigns an IP and information address for each host on the network, allowing them to communicate effectively with other endpoints.

Network Security (DDoS)

DNS SPF Record

In DNS (Domain Name System) an SPF record stands for sender policy framework and these SPF records indicate whether an email server is verified for a particular domain in order to prevent spoofing.

Network Security (DDoS)

What is a DDoS attack?

Distributed Denial of Service (DDoS) attack floods the target networks or server with traffic to exhaust its resources and bandwidth.

Network Security (DDoS)

What is a domain name?

An AAAA record (quad A record) is assigned the IPv6 to make the communication between the source and the destination. See how to create and use the AAAA record.

DNS

What is DDI?

DDI is the acronym for DNS, DHCP, and IP Address Management, the three core components of networking usually managed together.

What is an AAAA Record?

An AAAA record (quad A record) is assigned the IPv6 to make the communication between the source and the destination. See how to create and use the AAAA record.

DNS

DNS NS Record

A DNS NS Record is a set of data which nslookup, nsupdate and host reports return when queried. A NS record gives a site a domain email, name servers and IP addresses.

DNS

DNS SRV Record

A Domain Name System Service Record, SRV is short for service record.

DNS

DNS DMARC Record

A DMARC record is / TXT Record

Network Security (DDoS)

What is IPv6?

Internet Protocol Version 6 (IPv6) is a protocol for the network layer allowing data transfer via a switched network packet. The switching of packets requires data in packets from two nodes within a network to be transmitted and received.

DNS

Why do I need DNS management?

DNS is one of the most critical aspects of any network’s availability.  In an always-connected and technologically diverse world, it is essential for companies that want to have full visibility, authority, and control across networks at all times.

Network Security (DDoS)

What is Network Security?

Network security is a term for a set of features and best practices that offer protection against unauthorized access or abuse of the infrastructure of the network.

DNS

What is DNSSEC?

DNSSEC is a collection of protocols that provide a protective layer into the domain name system (DNS) scanning and sharing processes that are integrated into the Internet web access. DNSSEC is a set of protocols.
