Demystifying IPv4 Addressing & Subnetting

Wednesday, June 10th at 11:00AM EDT

IPv4 is the cornerstone of networking protocols and virtually all data utilize its services. And the most important aspect of IPv4 is the application of, and recognition of, IPv4 addresses. Join INE instructor Keith Bogart as he peels back the structure of IPv4 addresses and how network-capable devices use them to recognize IPv4 networks and hosts.




Keith started his networking career as customer service representative at Cisco Systems in 1996. His desire to learn more soon led him to a position as a Cisco Technical Assistance Center (TAC) engineer on the “Dial-Access” team, and within six months he had obtained his Dial-ISP CCIE. He later became a network consulting engineer and obtained his CCNA certification while teaching the technologies to Cisco employees during his lunch breaks. Keith was the first instructor on Cisco’s TAC Training team, where he taught a wide range of internetworking topics and later developed and taught other courses such as routing protocols, LAN switching, MPLS, 802.1x, and CCNA. After almost 17 years with Cisco, Keith joined a small startup and focused on 802.11 Wi-Fi technologies, during which time he obtained his CWNA certification. He is now very happy to be working with INE as an instructor for Routing & Switching. Keith lives in Raleigh, North Carolina, with his wife, son, and daughter. When he is not teaching INE Bootcamps, Keith can be found at home with his family, reading, or working in the yard. You may contact Keith Bogart at or find him helping others in INE’s IEOC Community Forum.
