Why is 192.168 always used?
Long story short, we are using 192.168.
X.X IP addresses because this is best practice.
The IETF has created three IP ranges for private networks, with Class C being the smallest and easiest to control and maintain.
This is why most routers use exactly this IP range..
What is a 24 subnet?
A class C network would have a subnet mask of 255.255. 255.0 which means that 24 bits are used for the network. In CIDR notation this is designated by a /24 following the IP address.
What is a 32 subnet?
the /32 is the CIDR (shorthand) and refers to how many 1’s are in the subnet mask. For /32 that is 255.255.255.255 or 11111111.11111111.11111111.1111111. that means you can only have one ip address, on your network before needing a gateway/router to get outside that network. with /32 it’s just you.
How many public IP addresses are there?

What is the IP address 0.0 0.0 used for?
In the Internet Protocol Version 4, the address 0.0. 0.0 is a non-routable meta-address used to designate an invalid, unknown or non-applicable target. This address is assigned specific meanings in a number of contexts, such as on clients or on servers.
Which of the following is the best definition of IP spoofing?
IP spoofing is the creation of Internet Protocol (IP) packets which have a modified source address in order to either hide the identity of the sender, to impersonate another computer system, or both.
What is highest IP address?
IPv4 uses 32-bit IP address, and with 32 bits the maximum number of IP addresses is 232—or 4,294,967,296.
What does 192.168 mean?
192.168. 1.1 – Computer Definition. The common default IP address of a router. Although it can be changed to another private IP addressing space, most of the time, the 192.168 range is used, and the default router address is left as is. See private IP address.

How do you subnet?
255.248 or /29.STEP 1: Convert to Binary.STEP 2: Calculate the Subnet Address. To calculate the IP Address Subnet you need to perform a bit-wise AND operation (1+1=1, 1+0 or 0+1 =0, 0+0=0) on the host IP address and subnet mask. … STEP 3: Find Host Range. … STEP 4: Calculate the Total Number of Subnets and Hosts Per Subnet.

What does 24 mean in IP address?
The number after the slash represents the number of consecutive 1’s in the subnet mask. For example, 192.168.10.0/24 is equal to the network 192.168.10.0 with a 255.255.255.0 subnet mask. If you convert 255.255.255.0 to binary, you end up with 24 consecutive 1 ‘s: 11111111.11111111.11111111.00000000.
Is 255.255 255.255 IP address valid?
No 255.255. 255.255 can’t be allocated to a host, because it is used as limited broadcast address(destination) i.e. when any host wants to broadcast information to all the hosts in its entire network it will assign the destination ip as 255.255. 255.255(ie send to all).
