The correct answer to this question is B, the IP address 184.108.40.206. Networks 220.127.116.11 through 127.0.0.0 are class A IP addresses. Networks ranging from18.104.22.168 through 22.214.171.124 are class B IP adresses. Networks ranging from 192.0.0.0 through 126.96.36.199 are considered Class C IP addresses.
The remaining numbers are for the specific device, using the 0-255 range, unless it's class C which uses the which goes up to 223. If an IP number falls outside and of the above ranges, then it is considered invalid and is rendered not valid for general use. The IP address in this answer, 188.8.131.52, would be considered a valid Class B IP address.
