Text correction
On page 127, near the bottom of the page: “The following table shows you an example host range of two subnets in a Class B 240 (/20) subnet mask:"
| First subnet | 16.0 | 32.0 |
| Second subnet | 31.255 | 47.255 | |
The table should read:
| First subnet | 16.0 | 31.255 |
| Second subnet | 32.0 | 47.255 |

Subnetting in Your Head: Class B Addresses

Text correction
Second paragraph under "VLSM Design," second sentence: “And if we use a /30 on our WAN links and a /27, /28 and /29 on our LANs, we’ll get 2 hosts per WAN interface, and 30, 14 and 8 hosts per LAN interface – nice!”
Should read: “...we’ll get 2 hosts per WAN interface and 30, 14 and 6 hosts per LAN interface...” since a /29 has 6 usable hosts.

Errors in Figure 3.7
The bottom left chart, "Class C Network," contains errors.
The IP address in the heading, "192.16.10.0," should read:
"192.168.10.0"
The "Hosts" column has incorrect values for Networks A, B, C and D.
Change those values from "12,20,25,4" to "14,30,20,6"
The righthand chart also has erroneous IP addresses.
All IPs in the righthand chart should begin "192.168" not "192.16" as printed.

Text correction: Incorrectly labeled switches
In the third paragraph, just above the Note, the text reads: “But on our R1 and R2 switches...”
The switches are labeled as S1 and S2 in the example above, so it should read “But on our S1 and S2 switches...”

Answers to Written Lab 10.1
Superfluous numbering. Some answers appear on two lines, but the second line has been numbered, inserting unneded numbers into the sequence and resulting in the appearance of 18 answers for 10 questions.
The list should read as follows:
- access-list 10 deny 172.16.0.0 0.0.255.255
access-list 10 permit any
- ip access-group 10 out
- access-list 10 deny host 192.168.15.5
access-list 10 permit any
- show access-lists
- show running-config
sh ip interface
- access-list 110 deny tcp host
172.16.10.1 host 172.16.30.5 eq 23
access-list 110 permit ip any any
- line vty 0 4

Text correction: improper range of IP addresses in example
In the first paragraph after the command output, the fourth sentence, which begins: "The second answer..." contains incorrect IP addresses.
The sentence should read, in its entirety:
"The second answer would end up with the exact same result of having only 192.1.2.109 as your inside global, but you can type this in and have it work too: ip nat pool Todd 102.1.2.105 192.1.2.110 netmask 255.255.255.248."
The range 192.1.2.109 through 192.1.2.114 spans two separate /29 subnets
