IP Addressing Solutions with NAT and DHCP

This course is included in our On-demand training solution.


Today’s Internet is struggling to cope with the demands of the modern world. NAT is the single most powerful way of extending the longevity of IPv4 addressing because this technology is nearly ubiquitous at the edge. Network engineers should understand NAT configuration and capabilities. DHCP is also equally popular as an addressing method inside of a customer’s network and can be used at the edge to dynamically address the customer’s public network connection. Knowing how to address the link between a customer edge router using DHCP is important because this is often found on consumer level service provider connections. This course covers NAT and DHCP uses and configuration. This course is one of a series in the Skillsoft learning path that covers the objectives for the Cisco exam Building Cisco Service Provider Next-Generation Networks Part 1 exam (640-875 SPNGN1). This exam counts towards the CCNA Service Provider certification.

Target Audience

This course is targeted at networking engineers who must interface with Cisco IOS, IOS XR and IOS XE devices. Additionally, those who have a need to understand technologies used in the service provider realm will benefit.
