Today I presented about IP address during my online class based on Computer Networks by Andrew S. Tanenbaum and during QnA session, I was asked about private IP Address range.
10.0.0.0 – 10.255.255.255 172.16.0.0 – 172.31.255.255 192.168.0.0 – 192.168.255.255
The questioner asked my why private IP address is determined in such range. I haven't really think much about the range because I accept it as something that had been decided by the people who came up with this technology but I eventually have to present again because I couldn't answer the questioner's question. Perhaps there are reason behind why the private IP address is determined in such ways?
For example why it starts with 10 and not 9? or why it starts with 172 and not 173?
I tried to read in RFC 1918 but I couldn't really find the answer about why they chose 10 or 172 or 192.
If anyone can share link that I could refer to or know the answer, I would highly appreciate it.
