255.255.31.0 how many number of subnet bits is there if it is subnet mask

Question

If it is super net mask how many super net bits is there

Answer 1

its a subnet of class B . so 16 net 16 host id .

255.255.31.0 = 

255.255. 00011111.00000000 there are 8+3 = 11 0`s 21 1`s

so no. of subnet possible 2^(21-16 ) = 32   

Supernet means combination of two or more networks (or subnets) with a common Classless Inter-Domain Routing (CIDR) . So max supernet subnet mask for this will be Class b subnet mask . 255.255.0.0 .

Number of subnet bits are 8
