Subnet ?

what is the subnet mask for the IP scheme 10.1.1.1 ?  Is it a /24  and a 255.255.255.0

10.x.x.x is a private IP range. You can use any or all of it with your private network.  So a network mask from 255.0.0.0 through 255.255.255.254 would work.

The mask of 255.255.255.0 is fine and will give you an IP range of 10.1.1.0 through 10.1.1.255.

You can make it anything you want.
10.0.0.0/8 is the default mask for this class A network
10.1.1.0/24 is a perfectly acceptible subnet mask
/24 = 255.255.255.0
          8 +  8 + 8 + 0 = 24 mask bits

Depends on how you're trying to subnet. It can be anything with a subnet mask that's at least 8 bits long.

As lrmoore as already said, /24 and 255.255.255.0 are the same thing when you're discussing subnet masks.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

if you are being classfull then the awnser would be 10.x.x.x. however if you want the easyest awnser just assign a new subnet mask. this will determin where the network part of the address ends and where the  host part starts for example


00001010.00000001.00000001.00000001 = 10.1.1.1
11111111.00000000.00000000.00000000 = 255.0.0.0
if you use and logic to put them togeather you get
00001010.00000000.00000000.00000000 = 10.0.0.0 (network address)

Vs if you change the subnet mask to say 255.255.255.0 then you get

00001010.00000001.00000001.00000001 = 10.1.1.1
11111111.11111111.11111111.00000000 = 255.255.255.0
if you use and logic to put them togeather you get
00001010.00000001.00000001.00000000 = 10.1.1.0 (network address)

the 0's represent the number of hosts that will fit in this network in this case it is 254 (256 subtract 1 for a broadcast address and 1 for the network address)

The quick an easy answer, without further information, would be to assume it's its natural class A - 10.0.0.0/8.

Unless they're subnetted, any network with the beginning octet less than 128 has a "natural mask" of 255.0.0.0.

i guess in retrospect my awnser was not as easy as as i thought it was lol.

Hi,

Now subnet is easy for you see please following links

You can also check the subnet mask through the following link
