Understanding NAT and DHCP | Working | Importance | Concepts

Video on IP address (last video) : https://www.youtube.com/watch?v=rZBkq5yAPW8 Networking Playlist : https://www.youtube.com/watch?v=M_KwiI_XOlY&list=PLUhdoQx6gMwKPVjD_-4TImIyhBQ0LzwLZ NAT stands for Network Address Translation . As the name implies it works for translating Addresses. See suppose i have a router (with NAT enabled on it) the ISP will assign me a public ip address (to the router) and all internal devices will have a private IP (all devices connected to the router). So when a device wants to connect to any device on the internet (i mean out of my LAN network or say wants to communicate to any device on other side of the router) the private IP will be converted to Public IP (because the world of internet understands public IP as that is global address) and this is done via NAT. DHCP stands for Dynamic Host Configuration Protocol. As the name implies this protocol is used to assign dynamic addresses to devices. Being more precise it manages the IP addresses and also configuration parameters like Subnet Mask, Default Gateway, Default Server, DNS Server etc. This is called DHCP because it handles all the necessary parameters required to configure network. Your IPS will use DHCP to handle assigning of public IP addresses and you can use DHCP to handle assigning of Private IP addresses (also public ones in case you have more than one public IP). #NAT #DHCP #networking
