Anyone with network experience in here? Help me with this question
How many /29 subnets are possible in the following range?
Block: 192.168.1.0
Net mask: 255.255.255.0
Gateway: 192.168.1.1
We're not doing your IT homework, Sandip.

at least 0

it's not homework. I'm trying to figure out networking and if someone can explain the answer to me, it would be very informative and I can use it to make understanding the material better

Took me 10 min to figure it out, what the hell op

32

2^(29-24)
kil urself op

yes i know 32 would seem like the answer because "google" but I just want to know if it IS the right one because of the provided Block address and a different net mask

a /29 has 2^(32-29) = 2^3 = 8 ip addresses
192.168.1.0 with a netmask of 255.255.255.0 = 192.158.1.0/24 = 256 IP addresses
256 / 8 = 32 8-ip address subnets possible in that block
FYI, it helps to think of IP addresses in the 4 blocks of 8-bits that they represent; a /29 means the last 3 bits can change with 2^3 possible permutations

IPv4 is such a shitshow. It's goddamned embarrassing that IPv6 found a way to be even worse.
Why can't we have a sane, consistent, 128-bit address protocol?
>>55116864
thank you for that information.
just to clarify the answer is 8 since the question is asking for possible subnets not IP addresses
>>55116864
Actually 6 usable adresses per block because you can't use the network and broadcast addresses

IPv4 grew over time. Back when it was developed, nobody even thought about network sizing, there were only three sizes: A, B and C. Then they discovered this to be a MASSIVE waste (bunch of companies still sitting on A networks, I believe General Motors owns the whole 3.0.0.0/8 range - What do you need that many public IP addresses for if you're not an ISP?) and developed subnet masks.
This then fucked with the routing protocols back then because they didn't have fields to advertise subnet masks, so new versions (RIPv2 etc.) had to be developed.
Then they discovered that subnet masks were still a massive waste because you couldn't make differently-sized networks and a router-to-router-link only needs two addresses. Then they developed VLSM, which fucked with the routing protocol implementations because they would get automatically summarized.
IPv6 has been around since the nineties and afaik there's still no true complete RFC out that's not experimental or such. The solution to subnetting problems was to stuff so much space into it that you wouldn't ever run out of addresses (they thought that about IPv4 too ...).
WHO THE FUCK HAD THE IDEA TO SEPARATE THE BLOCKS WITH COLONS???
If you want to connect to an alternate port, you need to enter [xx:xx:xx:xx::x:x]:8080.
IPv6 is already outdated (its been around for 20 years) and still not used. It's time to develop IPv8!

The possible subnets are 2^5 = 32 tho

IPv6 was outdated the day before it was debuted.
