What is a slash 30 subnet mask?
As you know a /24 bit subnet mask has 254 usable IP addresses + 1 for the broadcast + 1 for the network. This is calculated 2^8 (or 2 to the 8th power) = 256 – 2 = 254. So what is a /30 bit mask? A /30 bit mask would be 30 one’s, leaving just 2 zero’s that could be used for host addressing.
What does wear a 255.255 255.0 mean?

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.
What is a 255.255 255.255 subnet mask?
A network with a subnet mask of 255.255. 255.255 puts each device inside its own subnet, forcing them to communicate with the router before communicating with any other device.
What is the purpose of 127.0 0.0 IP address?
Network 127.0. 0.0 is reserved for IP traffic local to your host. Usually, address 127.0. 0.1 will be assigned to a special interface on your host, the loopback interface, which acts like a closed circuit.
What does 28 mean in IP address?
Answer: 28 is a subnet mask. IP address has 32 bits in total. 28 denotes network ID while rest of the bits (which are 4 bits) are used for hosts.
How are the netmasks used in slash notation?
The following table shows the netmasks in a binary form. The ‘CIDR’ column is the number of ‘1’s from left to right. This also known as ‘slash notation’. What used to be class A is now ‘/8’, B is ‘/16’, C is ‘/24’ and ‘/32’ is the ‘netmask’ for a single host. Netmasks are used by routers to make routing decisions.
When to use a / 31 subnet mask?
The use of /31 networks is a special case defined by RFC 3021 where the two IP addresses in the subnet are usable for point-to-point links to conserve IPv4 address space. Not all operating systems support RFC 3021, so use it with caution.
