Types

type Resolver

type Resolver struct {
	// contains filtered or unexported fields
}

Resolver represents a dns resolver for removing wildcards

func NewResolver

func NewResolver(domain string, retries int) (*Resolver, error)

NewResolver initializes and creates a new resolver to find wildcards

func (*Resolver) AddServersFromFile

func (w *Resolver) AddServersFromFile(file string) error

AddServersFromFile adds the resolvers from a file to the list of servers

func (*Resolver) AddServersFromList

func (w *Resolver) AddServersFromList(list []string)

AddServersFromList adds the resolvers from a list of servers

func (*Resolver) LookupHost

func (w *Resolver) LookupHost(host string) (bool, map[string]struct{}, string)

LookupHost returns wildcard IP addresses of a wildcard if it's a wildcard. To determine, first we split the target host by dots, create permutation of it's levels, check for wildcard on each one of them and if found any, we remove all the hosts that have this IP from the map.
