IP whitelist
New
Important:
To set the IP whitelist, contact the system administrator.
Only release as many IP address ranges as necessary. The larger the
released address range, the greater the danger of attacks.
IP address
The telephone supports the IPv4 Internet protocol, with a prefix length of 0
to 32 bits.
Network prefix (CIDR)
The network prefix provides the net mask for the IP address and specifies
how many IP addresses are released in a network range. The larger the
network prefix, the fewer the number of IP addresses that are released.
