Essential IP addressing and subnetting training course description
A course focusing purely on IP addressing and subnetting. The course assumes that delegates already have some knowledge of IP addressing. In particular delegates will be able to calculate subnet numbers in seconds without using binary.
Who will benefit?
Anyone working with TCP/IP.
Essential IP addressing and subnetting training course prerequisites
TCP/IP Foundation.
Essential IP addressing and subnetting training course objectives
By the end of the course delegates will be able to:
- Calculate subnet numbers in seconds.
- Design IP addressing schemes.
- Troubleshoot IP address problems.
- Calculate CIDR prefixes in seconds.

Essential IP addressing and subnetting training
course contents
IP addressing review
What is an IP address? What is a subnet? Classless IP addressing. The rules of IP addressing. Ways IP addresses are used: On hosts, in packets, in routing tables. Exercise: Byte boundary subnetting.
Configuring IP addresses
Interfaces, Static vs. dynamic configuration. DHCP: Scopes, leases, relays, using multiple DHCP servers. Multihoming.
Subnetting
Default subnet masks, subnet notations. How to subnet without binary. VLSMs. Exercise: Bit boundary subnetting.
Address ranges and routing
Routing tables, IP address spoofing, host specific routing, subnets in routing tables, supernets in routing tables. CIDR. Impact of choice of routing protocol. Exercise: IP addressing plans
Allocations and assignments
IAB, IANA, RIRs, RIPE, LIRs and ISPs. PI vs. PA addressing. Exercise: Querying the RIPE database.
Private addressing and NAT
NAT, NAPT, NAT terms, private addresses, NAT operation, NAT architecture, NAT and security, why use NAT? NAT-ALG, Types of NAT, RSIP.
Special use addresses
Unicasts, broadcasts, multicasts, anycasts. Directed broadcasts. Allowing broadcasts through routers.
