What is a 31 bit mask?
31-bit Subnet Mask (/31) A 31-bit subnet mask is often used for an interface that is the endpoint of a point-to-point network. The use of 31-bit subnet masks for IPv4 point-to-point links is described in RFC 3021. For 192.168.0.0. Router A is connected via Fast-ethernet 0/0 having ip 192.168.
What is the subnet mask using 24 bits?
A class C network would have a subnet mask of 255.255. 255.0 which means that 24 bits are used for the network.
What is the maximum usable host for 23?
Class A
| Network Bits | Subnet Mask | Number of Hosts |
|---|---|---|
| /23 | 255.255.254.0 | 510 |
| /24 | 255.255.255.0 | 254 |
| /25 | 255.255.255.128 | 126 |
| /26 | 255.255.255.192 | 62 |
Which wildcard mask would permit all hosts from the 192.168 10.0 24 network?
Wildcard Mask to Match an IPv4 Subnet In this example, ACL 10 needs an ACE that permits all hosts in the 192.168. 1.0/24 network. The wildcard mask 0.0. 0.255 stipulates that the very first three octets must match exactly, but the fourth octet does not need to match.
What is a slash 31?
Using a /31 subnet mask helps conserve your IP address space for point to point links. It doubles the number of links that you can number from a given block of addresses. Think of large organisations that have hundreds of WAN links but are rapidly running out of address space.
When would you use a 32 subnet mask?
Generally speaking, /32 means that the network has only a single IPv4 address and all traffic will go directly between the device with that IPv4 address and the default gateway. The device would not be able to communicate with other devices on the network.
