Explore Networking In The Cloud

Week 2 Announcement

We are approaching Week 2, and you continue exploring networking in the cloud.  In Step 3, learn about TCP - the other part of TCP/IP pair of protocols. It ensures reliability of Internet communications composed of IP packets. In Step 4, explore IP subnetting - a way of grouping IP addresses to help use them efficiently.  There is an interim submission in Step 4, and here are the details:

Ballot Online has been assigned the following block of Class B IP addresses:

172.16.192.0/19

It allows for up to 2 to the power of 32-19 which is 13, i.e. 8192 IP addresses.

Ballot Online wants to open 4 field offices, with up to 2000 IP network hosts (desktops and other externally accessible networked devices) each.

Design the 4 subnets for these field offices. For each subnet, show the subnet mask, network and broadcast addresses in x.x.x.x decimal format as well as 32-bit binary (0 or 1) bitmaps, and the range of usable host addresses within the subnet.
