Course description

TCP/IP, or Transmission Control Protocol/Internet Protocol, is used to control how computer systems connect to the internet. And in this extensive course with one of our most experienced instructors, you’ll rediscover the world of TCP/IP. You’ll look at subnet masks, classful addressing, rogue DHCP servers, special IP addresses, Network Address Translation (NAT), Routing Information Protocol (RIP) and much, much more!
