could you give me a hand with subnetting192.168.7.0/25 into two subnets A-with 110hosts and B-with 54hosts? i thought i had it but in my lab host B subnet mask has .192 (last octet) when i thought it was suppose to be .128. also i dont get what determines the gateway/default gateway.
@bigr5150 Sure no problem, it sounds like you need a subnet within a subnet or VLSM. Your first subnet could be 192.168.7.0 /25 (128 hosts) and your second subnet could be 192.168.7.128 /26 (64 hosts). I am guessing your gateway/default gateway question is in regards to a router. It depends on where you want your router to send traffic when it doesn't know the destination network. If you dont set up a Default GW then packets to unknown nets will be dropped
@danscourses ok i have the 1st subnet right, but i thought the 2nd was going to start at 192.168.7.129/25. how do i make the subnet within a subnet or vlsm, do u have a video showing that? also do you have to use a specific address for gateway/default gateway?
@bigr5150 the second subnet's network address is .128 and the first usable host is .129
Your gateway will be the ip address of the next hop router, it is not a specific address number. VLSM just means when the subnets are different sizes. Look up VLSM and you will find my video.
@danscourses i think i c, you have to add the first set of borrowed bits to the second set of borrowed bits and use that number to create ur addresses.
@mauroprovatos My guess is for classful routing, routers and computers are able to calculate default network masks based on an ip address' first order bits. For instance If the address starts with a 110 the netmask will be /24, 10 will be /16 and 01 or 00 will be /8

@danscourses
s this correct: first subnet:192.168.7.0/25 (128 host) and the 2nd subnet is 192.168.7.128/25 (128 host) ???
why did you put the 2nd subnet as /26 and the magic number u used is 64 since the magic number of /25 is 128

the 200.0.0.0 network is class A,according to the subnet mask
but class C according to the significant bits of the 1st octet since 200 (dec) is 11001000(bin)
what's up with that?
