Last week we covered chapter four which talked about the TCP/IP and the DoD models and what role they cover in networking as we learned that every application like FTP, DNS, DHCP depend on it. Like always post questions if you have any about the book CCNA Data Center Study Guide from Todd Lammle. I’ll continue to cover topics of each chapter of the book, plus any examples the book offers and to get an idea of what the Cisco exam would cover. Let’s go over chapter five.
Overview: I think we knew it was on the way, in this chapter we opened the door to IPv4 addressing. If this is your first time understanding IP addresses go over it carefully, this exam will cover it. Know the ranges of a Class A, B and C networks, where’s the loopback? Also know the private IP class ranges of A, B and C. (RFC1918) Know the difference between broadcasts, unicast, and multicast addresses. We also got introduced into IPv6, know the address format, the short hand way to write an IPv6 address as well as the types of IPv6 addresses. (link-local, unicast, global unicast addresses, and unique local address)
My thoughts: If you have been around IPv4 addresses you might be good on this chapter, towards the end of the chapter I would look at IPv6, we don’t talk about subnetting yet that’s next week. 🙂 Pretty short chapter this week post questions below if you have any on this chapter.
