This is a question I cannot solve myself, despite having the answer.
Question: Which one of the following can’t be a public Internet IP address?
a) 217.9.215.1
b) 197.165.276.1
c) 162.198.207.3
d) 174.158.254.203
Answer: b) 197.165.276.1
IANA private ranges are:
10.0.0.0 to 10.255.255.255
172.16.0.0 to 172.31.255.255
192.168.0.0 to 192.168.255.255
So why 197.165.276.1 can’t be a public IP address? Are there any extra private ranges not included in the IANA list ?
