I HAVE ONE QUESTION RELATED TO IP ADDRESS CLASS B. IF CLASS B CONTAINS ONLY 172.16.0.0 TO 172.31.255.255 AS PRIVATE IP ADDRESS RANGE THEN WHY OUR ADMINISTRATOR PROVIDE 184.108.40.206 TO 220.127.116.11 AS PRIVATE IP IN OUR ORGANIZATION.IN DNS SERVER IP WE PROVIDE 18.104.22.168.AND IN DEFAULT SUBNET MASK WE PROVIDE 255.255.240.0
I understand you question now. Inspite of the private IP range in the Class B range is 172.16.0.0 till 172.31.255.255, having a private IP address on the internet is of little or no consquence at all. Most routers will drop packet which contain either source or destination address as private, or even both. Also, the range used by your company might have something to do with network policies used by your own network administrator. Perhaps it will be a better idea to pose this question to that individual who has decided your company network to be built like that.
