Matcher provides fast IPv4 address matching

func NewMatcher

func NewMatcher(rangeList ...string) (*Matcher, error)

NewMatcher creates a Matcher with the ip ranges. IP range expression should be one of following formats:

• CIDR(ex. "10.0.0.0/8")
• raw IP(ex. "127.0.0.1")
• IP range(ex. "192.168.1.1 - 192.168.1.100")

func (*Matcher) Match

func (m *Matcher) Match(ipStr string) bool

Match reports whether the Matcher's ip ranges includes ip

Example

matcher, _ := NewMatcher("10.10.0.0/16", "10.20.0.0/16", "10.30.0.0/16")

fmt.Println(matcher.Match("10.10.10.10"))
fmt.Println(matcher.Match("10.100.100.100"))

Output:
true
false
