The configuration of a DNS server consists of a series of records. In this video, you’ll learn about the record types commonly seen in a domain name system server configuration. << Previous Video: An Overview of DNS Next: An Overview of NTP >> If you were to look at the configuration of a DNS server, […]

The Domain Name System is one of the most used technologies on the Internet. In this video, you’ll learn about the DNS hierarchy, recursive and iterative DNS queries, and forward and reverse DNS queries. << Previous Video: Configuring DHCP Next: DNS Record Types >> DNS is the domain name system. And it’s one of the

There are some important configuration options to use when configuring a DHCP server. In this video, you’ll learn about DHCP pools, scope properties, and the lease timers associated with DHCP. << Previous Video: DHCP Overview Next: An Overview of DNS >> Let’s say that you’ve been tasked with configuring a DHCP server, so you need

We rely on DHCP to keep all of our devices working. In this video, you’ll learn about the DHCP process and how to assign IP addresses using a DHCP on a different broadcast domain. << Previous Video: Other Useful Protocols Next: Configuring DHCP >> In the early days of TCP/IP, everything dealing with the configuration

As a network professional, you’ll work with many specialized and diverse protocols. In this video, you’ll learn about ICMP, GRE, VPNs, and IPsec. << Previous Video: Common Ports Next: DHCP Overview >> In this course so far, we’ve talked about two main types of protocols that you commonly see running inside of IP. It would

You can’t use an application unless you know the port number. In this video, you’ll learn about the common port numbers and how they are used to access network-based applications. << Previous Video: Introduction to IP Next: Other Useful Protocols >> As a network administrator, you will work often with TCP and UDP port numbers,

How does IP get our data from one side of the network to the other? In this video, you’ll learn about the fundamentals of IP and how IP addresses and port numbers are used on our modern networks. << Previous Video: Configuring IPv6 Next: Common Ports >> The data networks that we’ve created allow us

The need to subnet is minimized in IPv6, but there are still subnetting fundamentals that are important to know. In this video, you’ll learn about IPv6 subnetting and how most networks implement IPv6 subnet masks. << Previous Video: IPv6 Addressing Next: Configuring IPv6 >> On the internet, we have a formal process on how IP

Before you can use a shortcut to calculate subnet values, it’s useful to understand the binary math. In this video, you’ll learn how to calculate the important values of an IP subnet based on the IP address and subnet mask. << Previous Video: IPv4 Subnet Masks Next: Magic Number Subnetting >> In this video, we’ll

The IPv4 subnet mask determines which devices are on your local IP subnet. In this video, you’ll learn about the structure of the IPv4 subnet mask and how to calculate the subnet mask based on binary and CIDR-block notations. << Previous Video: Classful Subnetting Next: Calculating IPv4 Subnets and Hosts >> In this video, we’re
