Question

hey, can somebody help me with TCP/IP?

Answer 1

There needs a need for 50 hosts. What subnet mask should be use in order to have the most possible subnets.?

Answer 2

class C subnet mask, right?

Answer 3

255.255.255.192 should allow you to go up to 62 hosts (64 less all zeroes and all in the last 6 bits). "most possible subnets" means least excess host in each subnet.

Answer 4

since the IP address is 201.168.67.0
and the subnet mask is 255.255.255.192

does that mean I can only have four subnets?

Answer 5

Yep, if they are all 62 or less hosts. The mask looks like this:
11111111.11111111.11111111.11000000
giving the last byte for the four subnet addresses as:
.00000000
.01000000
.10000000
.11000000
