Essential Question: What is DNS? What is the purpose of DNS?

Objective: Learn hoe to configure the Domain Name System and how to understand server IP addresses.

What is up class!! We recently covered DHCP and APIPA last class. These deal with how IP addresses are given to computers on a network, now we’re going to look at the Domain Name Server. The DNS changes IP addresses from numbers to actual names, like www.coachearlyrocks.com. Check these videos that talk about DNS and explain how DNS makes it easier to search for websites online:

Essential Question: How do devices connected to a network get their IP address? Can they get an address without a server?

Objective: Explore the function of DHCP and APIPA in relation to network devices.

Yo, I can’t tell ya’ll how much I appreciate you guys behaving! Todays assignment is easy, just a few videos going over DHCP the service responsible for giving each device connected to a network, its IP address, and APIPA which is responsible for giving addresses when no DHCP is available   :

11-30 Class Instructions

Essential Question: How many subnet IP addresses can come from a specific subnet.

Objective: Manually configure IP addresses to match with needed devices in an organization.

Ok guys! Last we left off with IP addresses and subnetting. Its been a while, so I included a video that should catch us back up (Plus it should give me some time to get Testout back up for us) :

So as I was grabbing videos I also came across a GREAT video explaining CIDR notation. (basically how many IP addresses we can get from a subnet).

So watch this video and answer these questions posted below. Submit your answers to this google form and I’ll grade them!

Things to remember:

  • An IP address is a numbered address that devices use to connect to the network/internet.
  • We use IPV 4 currently, it looks like 192.168.1.1
  • IP addresses can be converted into binary, like: 192.118.011.022 would be 110000000.10100111.0001011.00010110
  • Remember to subtract 1 address from the total (because it is the broadcast and we cant use that address)

Questions:

  1. How many subnet addresses come from the IP address 192.168.1.1 /24
  2. How many subnet addresses come from the IP address 52.56.18.12 /28
  3. How many subnet addresses come from the IP address 127.0.0.1 /23

IP Calculate that!
