1 1 vote If I need to have a network of 509 hosts using class C,then do i need to join 2 Class c networks or 3? One class C gives us 256-2=254 hosts in case of subnetting.Does the same hold in case of super netting also?Or does in super netting one class c can give 256 hosts?

Best answer 2 2 votes Default mask of class C is 255.255.255.0 and maximum number of hosts supported by class C is 254. We cannot have a network of 509 hosts using class C, unless we use supernetting. Supernet mask of 255.255.254.0 would suffice to have a network of 509 hosts using class C. #networks = 2 #hosts = 29 - 2 = 510 just_bhavana answered Aug 9, 2017 • selected Dec 21, 2017 by rahul sharma 5 just_bhavana comment Share Follow See all 9 Comments 9 9 Comments reply Show 6 previous comments rahul sharma 5 commented Aug 9, 2017 reply Follow flag Ok,i understood your last comment.And this -2 is for network id and DBA? And you mentioned 255.255.255.0 where we have 8 0's for host bits which will give 254 hosts in you last commnet.Is this a valid supernet mask for class c? 1 1 replyShare just_bhavana commented Aug 9, 2017 reply Follow flag Yes -2 is for n/w id and DBA and 255.255.255.0 is the default mask of class C. 0 0 replyShare AnilGoudar commented Aug 9, 2017 reply Follow flag How to derive default supernet mask for other classes? 0 0 replyShare Please log in or register to add a comment.
