C.Net – Network Methods

C.Net.cidrMatch()

​

Net.cidrMatch(cidrIpRange: string, ipAddress: string): boolean

Determines whether the supplied IPv4 or IPv6 ipAddress is inside the range of addresses identified by cidrIpRange.

Examples

​

(IPv4): C.Net.cidrMatch('10.0.0.0/24', '10.0.0.100') returns true.

(IPv6): C.Net.cidrMatch('2001:db8::/32', '2001:db8:0:0:0:ffff:0:0') returns true.

C.Net.isIpV4()

​

Net.isIpV4(value: string): boolean

Determines if the value supplied is an IPv4 address.

C.Net.isIpV6()

​

Net.isIpV6(value: string): boolean

Determines if the value supplied is an IPv6 address.

C.Net.isIPV4Cidr()

​

Net.isIPV4Cidr(value: string): boolean

Determines whether a value supplied is an IPv4 CIDR range.

Returns true if the value is a valid IPv4 CIDR range; otherwise, false.

C.Net.isIPV6Cidr()

​

Net.isIPV6Cidr(value: string): boolean

Determine whether a value supplied is an IPv6 CIDR range.

Returns true if the value is a valid IPv6 CIDR range; otherwise, false.

C.Net.isIpV4AllInterfaces()

​

Net.isIpV4AllInterfaces(value): boolean

Determines if the value supplied is the IPv4 all-interfaces address, typically used to bind to all IPv4 interfaces – i.e., ‘0.0.0.0’.

C.Net.isIpV6AllInterfaces()

​

Net.isIpV6AllInterfaces(value): boolean

Determines if the value supplied is an IPv6 all-interfaces address, typically used to bind to all IPv6 interfaces – one of: ‘::’, ‘0:0:0:0:0:0:0:0’, or ‘0000:0000:0000:0000:0000:0000:0000:0000’.

C.Net.ipv6Normalize()

​

Net.ipv6Normalize(address: string): string

Normalizes an IPV6 address based on RFC draft-ietf-6man-text-addr-representation-04.

C.Net.isPrivate()

​

Net.isPrivate(address: string): boolean

Determines whether the supplied IPv4 address is in the range of private addresses per RFC1918.
