[Java software]
[Java proxy software]

Additional Activities

The additional activities for this week are:

Activity 7.1: Network addresses

IP addresses are not the only type of network address, as IPX and NetBEUI are two other ones [Link]

and:

Activity 7.2: IP address classification

IP addresses are grouped into different classifications [Link]

and:

Activity 7.3: Dotted notation

IP addresses have a binary format, this is then converted into a dotted notation to make it easier for humans to read [Link]

 

and

Activity 7.4: IP Allocation

IP addresses must be assigned correct, relating to the subnet they have been allocated to. Ports on routers must also have IP addresses allocated to them. [Link]

and

Activity 7.4: Subnet mask

Subnet masks are important as they tell devices as to the network part and the host part of an address [Link]

Challenge

The challenge for this week is:

Challenge 4

Networks are segmented using routers, which limit broadcast domains, and allow data to flow from network to network. [Link]
