Domain Name Services are a critical part of any network. In this video, you’ll learn about DNS, local name resolution, forward and reverse lookups, recursive queries, and securing DNS. << Previous: IPv6 and SLAAC Next Video: DNS Records >> One of the most common uses of DNS, or the Domain Name System, is to translate […]

Automatic addressing is part of the IPv6 standard. In this video, you’ll learn about SLAAC, Network Discovery Protocol (NDP), and automatic addressing of IPv6 devices. << Previous: Configuring DHCP Next Video: An Overview of DNS >> With IPv6, we’ve taken a number of techniques we’ve used with IPv4, and we’ve updated them for the modern

Configuring a DHCP server requires a number of different settings. In this video, you’ll learn about DHCP pool, address reservations, DHCP options, the lease process, and more. << Previous: DHCP Next Video: IPv6 and SLAAC >> In our previous video, we looked at the process of DHCP from the client’s perspective, but obviously there are

We rely on the Dynamic Host Configuration Protocol to automatically assign addresses to our network devices. In this video, you’ll learn about the DHCP process and how DHCP relay can be used to design a more efficient DHCP process. << Previous: Network Redundancy Next Video: Configuring DHCP >> On our modern networks, we’ve become so

Keeping systems running is an important part of any network design. In this video, you’ll learn about active-active configurations and active-passive configurations. << Previous: Disaster Recovery Next Video: DHCP >> Maintaining uptime and availability on the network can be a challenge. And in this video, we’ll look at different methods for providing that network redundancy.

It’s important to plan for any contingency. In this video, you’ll learn how to measure outages, options for site resiliency, and how to prepare and test for a disaster scenario. << Previous: Network Solutions Next Video: Network Redundancy >> Most organizations will create a plan that they will follow if they happen to have an

There are many different methods for managing the network. In this video, you’ll learn about network discovery, traffic analysis, availability monitoring, and more. << Previous: Logs and Monitoring Next Video: Disaster Recovery >> When you sit down to troubleshoot a network issue, you’re starting with no information. So we need to start gathering more details,

The network never sleeps. In this video, you’ll learn how to monitor the network using flow data, protocol analysis, Syslog, SEIMs, and more. << Previous: SNMP Next Video: Network Solutions >> On your network, you’re probably using routers, switches, firewalls, and many other network infrastructure devices. And all of these devices are running 365 days

The Simple Network Management Protocol is widely used for monitoring and configurations. In this video, you’ll learn about SNMP versions, SNMP traps, and the authentication process used by SNMP. << Previous: Configuration Management Next Video: Logs and Monitoring >> As a network administrator, you will install switches, routers, servers, firewalls and many other pieces of

The configuration of a device can be the most important part of the system. In this video, you’ll learn about production configurations, backup configurations, and baseline configs. << Previous: Life Cycle Management Next Video: SNMP >> Change is inevitable. And we need to have some type of process on our network to be able to
