Finding subnet 300

[josephtbr]

Hello everyone i am a student and need help with a question

Assume a network topology has a network address of 99.0.0.0.

if 11 bits are used as a subnet bits hence subnet mask would be 255.255.224.0

Question asks to calculate the subnet address for Subnet 200 and Subnet 300?

Subnet 200 would be 

99.1100 1000.0000 0000. 0000 0000

= 99.200.0.0

how do i calculate the subnet address for subnet 300 if it has more than 255 bits?

In a sidebar private discussion with @MHM Cisco World , provided the following examples of the original Class A address with an 11 bit subnet, showing how subnets 1, 8, 9, 200 and 300 are done in binary and IPv4 dotted decimal.  Possibly this might help others too.

Examples of using that subnet allocation and its dotted decimal representation:

nnnnnnnn ssssssss ssshhhhh hhhhhhhh
01100011 00000000 00100000 00000000

99.0.32.0/19 = subnet 1 (binary 1), using an 11 bit subnet

nnnnnnnn ssssssss ssshhhhh hhhhhhhh
01100011 00000001 00000000 00000000

99.1.0.0/19 = subnet 8 (binary 1000), using an 11 bit subnet

nnnnnnnn ssssssss ssshhhhh hhhhhhhh
01100011 00000001 00100000 00000000

99.1.32.0/19 = subnet 9 (binary 1001), using an 11 bit subnet

nnnnnnnn ssssssss ssshhhhh hhhhhhhh
01100011 00011001 00000000 00000000

99.25.0.0/19 = subnet 200 (binary 11001000), using an 11 bit subnet

nnnnnnnn ssssssss ssshhhhh hhhhhhhh
01100011 00100101 10000000 00000000

99.37.128.0/19 = subnet 300 (binary 100101100), using an 11 bit subnet
