Hello Mr. Rene I m new in the community. I m familiar with basics cisco Routing and Switching but I m not certified yet. I plan to pass my certification soon (ICND1 and 2). In the ICND1 programm, I don’t see IPV4 subnetting (VLSM, CIRD, IP subnetting…) in the chapter “Introduction to Internet Protocol Version 4 (IPV4)”. Is this no loger part of Cisco ICND1? Best Regards. ---

Hello Mbaye Take a look at Cisco’s official list of topics for ICND1: [https://learningnetwork.cisco.com/community/certifications/ccna/icnd1/exam-topics](https://learningnetwork.cisco.com/community/certifications/ccna/icnd1/exam-topics) It doesn’t include VLSM, CIDR but does include IP subnetting and addressing. Rene has a subsection on subnetting in the ICND1 course that you can find here: > **[CCNA 200-301 - NetworkLessons.com](https://networklessons.com/cisco/ccna-200-301)** > > The CCNA 200-301 course explains everything you need to know to prepare for and pass the Cisco CCNA 200-301 exam. The subsection is included under the IPv4 section: ![image](https://cdn-forum.networklessons.com/uploads/default/original/2X/1/156ec32d4b6fd6819c32222fef7cf7df8d154a74.png) I hope this has been helpful!
