Netmask

newNetmask(str) → Netmask

newNetmask(ca, bits) → Netmask

New in version 1.5.0.

Returns a Netmask

Parameters:

• str (string) – A netmask, like 192.0.2.0/24.
• ca (ComboAddress) – A ComboAddress.
• bits (int) – The number of bits in this netmask.

class Netmask

New in version 1.5.0: Represents a netmask.

:getBits() → int

Return the number of bits of this netmask, for example 24 for 192.0.2.0/24.

:getMaskedNetwork() → ComboAddress

Return a ComboAddress object representing the base network of this netmask object after masking any additional bits if necessary (for example 192.0.2.0 if the netmask was constructed with newNetmask('192.0.2.1/24')).

:empty() → bool

Return true if the netmask is empty, meaning that the netmask has not been set to a proper value.

:isIPv4() → bool

Return true if the netmask is an IPv4 one.

:isIPv6() → bool

Return true if the netmask is an IPv6 one.

:getNetwork() → ComboAddress

Return a ComboAddress object representing the base network of this netmask object.

:match(str) → bool

Return true if the address passed in the str parameter belongs to this netmask.

Parameters:str (string) – A network address, like 192.0.2.0.

:toString() → string

Return a string representation of the netmask, for example 192.0.2.0/24.
