Lab 5 1: IP Subnet Mask Exercises - CSchulz0618/Network-Fundamentals GitHub Wiki

In this lab we learn how to use binary in IP Addresses and find Host and Network IDs and also how to subnet.

How do you convert a single octet within an IP address from decimal to binary?

128, 64, 32, 16, 8, 4, 2, 1

  • 00000000

How do you find the network and host ID within an IP address?

  • The Network ID is the first digits of the IP that Identifies the network and the host ID is the digits afterward that represents the host.

How do you create a subnet ID within an IP address?

  • All of the Network ID become 1s and 5 out of the 8 bits become 1s in the subnet masks and then calculate from the original host ID. (Binary Math)
