Networking Reference Section

Networking is a major topic in penetration testing. In this appendix, I have gathered together all the important information so that you can refer to it when you need to.

Network subnets

Sometimes, you will be given subnet masks (a range of IP addresses) to test, and in some cases, you will test only one single IP address. If you're using a subnet mask, then use the following table as a reference:

CIDR Hosts Net mask
/30 2 255.255.255.252
/29 6 255.255.255.248
/28 14 255.255.255.240
