The mask is a number in the range of 0-32, which
indicates the number of bits in the IP address that remain
unchanged for the IP addresses in that block. The
remaining bits in the IP address should be all 0s. The
address block includes all addresses except for the first
address and the last (x.x.x.255) address.
For example:
144.195.0.0/16.
All addresses in the range from 144.195.0.1 to
144.195.255.254
144.195.1.2/32
The host itself 144.195.1.2
0.0.0.0/0
All the IP addresses in your network
224.0.0.0/4
All the class D multicast addresses, from 224.0.0.1 through
239.255.255.254
3DES2key Specifies Three stage Cipher Block Chaining. 3DES2key
must be at least 16 bytes long for x xS packages. The
3DES2key key is constructed using the first 8 bytes for both
encrypt phases, and the second 8 bytes for the decrypt
phase of the encrypt-decrypt-encrypt (
EDE) transform.
DES Specifies Cipher Block Chaining mode of the Data
Encryption Standard. DES keys must be at least 8 bytes
long.
RC5 Specifies encryption used with Microsoft Point to Point
Ecryption (MPPE). RC5 keys must be at least 5 bytes long,
and may be up to 7 bytes with xE packages or up to 15
