About IP Addressing and Subnetting

GoConqr Original

What the page covers

This unit sits in the Addressing and Protocols strand of Networks and telecommunications. It starts with the basics of IPv4 and moves on to subnetting, address translation and IPv6. The resources were made by GoConqr users, so styles differ, and some are in Spanish or German.

Where to begin

Start with the mind map IPv4 Addressing. It sets out the rule that addresses in one group must not be separated by a router, and that addresses divided by a router belong in different groups. Then try the IPv4 Address Flash Cards, which ask for the range of each class from A to D. Pair them with the map on IPv4 address classes based on first-octet values.

Moving on to subnetting

Once classes feel familiar, work through the quizzes in order:

  1. The quiz on Chapter 14 of the ICND 1 guide, which asks how network, subnet and host parts fit together.
  2. The quiz on perspectives on IPv4 subnetting, which asks which devices share a subnet with a PC on VLAN 1.
  3. The VLSM review questions, which explain why a /30 mask suits a point-to-point WAN link, since such a link uses only two hosts.

The several Subnetting Procedures maps and the Powers of 2 flashcards help with the arithmetic behind these questions.

NAT, DHCP and IPv6

The E2_11 NAT flashcards explain how private IPv4 space is translated to public addresses, which must be registered with a Regional Internet Registry. Maps and notes on DHCP cover address assignment. For IPv6, look at the maps and the flashcards on IPv6 header details and special addresses. Anyone working on server tools can follow the flowchart on deploying IP Address Management.

Using quizzes and maps together

Read a map first, then take a quiz on the same topic. Wrong answers show which map branch to revisit. Several resources are tied to CCNA and BCS study, so use the exam-style quizzes once the basics are steady. Choose one topic today and open a quiz to see where you stand.

Frequently asked questions

Which resource should I open first?

Begin with the IPv4 Addressing mind map, then the IPv4 Address Flash Cards. They cover grouping rules and class ranges, which the subnetting quizzes assume. After that, move to the quiz on Chapter 14 of the ICND 1 guide and carry on through the subnetting quizzes.

What do the mind maps cover?

The maps span IPv4 classes, network and host bits, subnetting procedures, NAT for IPv4, DHCP and IPv6. Some are in Spanish. There are over 120 of them, so you can usually find one for the topic you are revising before trying a quiz.

Are these resources free to use?

Yes. Every resource listed here is free to open, study and take, with no account needed. A free account also saves your quiz scores and lets you make your own quizzes, mind maps, flashcards and notes.

Which exams do the resources relate to?

Resources on this page mention CCNA and BCS. You will find CCNA-style subnetting quizzes, a CCNA 200-301 flashcard deck and practice exams. The level mix leans towards university students and professional candidates, so the material suits both.

Who made these resources?

They were made by GoConqr users, not by GoConqr itself. Over 170 contributors have added quizzes, maps, flashcards, notes and slides, so teachers can also pick items to share with a class.

What if I cannot find what I need?

Try a nearby topic. Subnetting appears under several titles, such as Subnetting Questions and Subnetting IP Networks. You can also make your own map or flashcards on the missing point.
