Study question

mgmguy1

So I was doing an ICND1 exam quiz on my Measure up CD when I had this question.


Is 192.168.20.5 a Public or Private IP address ?

I answered it was Private but the test said it was public.

Correct me if I am wrong here but I was under the impression anything that is 192.xxx.xxx.xxx is a privet address not public.


Please advise.
Patrick

Actually, it's 192.168.XXX.XXX, but, yeah, it looks pretty private to me, too.

   The Internet Assigned Numbers Authority (IANA) has reserved the
   following three blocks of the IP address space for private internets:

     10.0.0.0        -   10.255.255.255  (10/8 prefix)
     172.16.0.0      -   172.31.255.255  (172.16/12 prefix)
     192.168.0.0     -   192.168.255.255 (192.168/16 prefix)
