func ToCIDR ¶

func ToCIDR(ipStr, maskStr string) string

ToCIDR converts an IPv4 address and a netmask string into CIDR notation. It returns an empty string if the input IP or mask is invalid. For example, given "192.168.0.1" and "255.255.255.0", it returns "192.168.0.1/24".

func ToIpMask ¶

func ToIpMask(cidr string) (string, string)

ToIpMask takes an IP address in CIDR notation (e.g., "192.168.100.2/24") and returns the IP address and its corresponding netmask string (e.g., "255.255.255.0").
