Information About the HTTP 1.1 Web Server and Client.

This module describes the concepts and tasks related to configuring the HTTP 1.1 Web Server and Client feature. When combined with the HTTPS feature, the HTTP 1.1 Web Server and Client feature provides a complete, secure solution for HTTP services between Cisco devices. I tried to explain things in simple manner however things are more complicated in real world, but it's good enough to get basic level understanding that how things work out there.The HTTP 1.1 Web Server and Client feature provides a consistent interface for users and applications by implementing support for HTTP 1.1 in Cisco IOS software-based devices. You need to setup domain name and user accounts to simulate emails.

Next TLD is going to delegate Zones to SLDsĪfter setting up next you need to setup Web Application or Email Server so I've setup both.

Next thing is Root will delegate TLD partition or Zone to Com Server (you can use whatever you want like. So, to simulate email first you need to setup DNS !!!Īs shown in the above illustration you need to setup Root, Com and Second Level DNS Servers. That's why DNS is tightly coupled with Email systems. Emails use Domains !!! for example is a domain and is an email address which is in human readable English language. Millions of people around the world send and receive emails on daily basis. So What's the link between Email and DNS? Second Level Domains (Microsoft, Facebook, Google).Top Level Domains ( Com, Net, Org, Mil, Biz).Whenever you type in your browser the DNS comes to play which resolves the to some IP address .īasically DNS is a hierarchical database which is categorized in domains, the specific partition for that domain in DNS server is called a Zone, all stuff related to that specific is contained in a DNS Zone.

Let's Talk about DNSĭNS (Domain Name System) is used to resolve name to IP address to make things simple for humans, yes absolutely for us ! Have you ever think how it works behind the scene? Think DNS as your phonebook where you have saved hundreds of numbers but you call them by names only !!!ĭoes it make sense? exactly this is how DNS works for you. Note: Github link is provided at bottom to download. In this article you will learn how to simulate DNS and Email simulation to understand how it's works in real world? Aswe all know that Cisco Packet Tracer is usually used to simulate Networking scenarios but what else you can do with this tool? Yup ! we can do a lot of stuff with Cisco Packet Tracer like Web Server, Email Server, DNS Server etc.
