Types ¶
type Client ¶
type Client struct {
// contains filtered or unexported fields
}
Client to resolve hosts and ip addresses
func (*Client) DoAXFR ¶
DoAXFR attempts to execute an AXFR against a domain by first getting the domains NS records, and attempts an AXFR against each server. We use a waitgroup for NS servers and a workerpool for doing resolution on various records returned by AXFR.
func (*Client) DoNSECWalk ¶
DoNSECWalk walks NSEC records, following NextDomain until it's empty, or points back to the original starting address.
func (*Client) IsWildcard ¶
IsWildcard tests if a domain is a wildcard domain, attempt 10 A and 10 AAAA queries of randomly generated names, if we get even a single response it's probably a wildcard
type Results ¶
type Results struct {
IPs []string // a slice of ip addresses returned from a request
Hosts []string // a slice of hosts returned from a request
RecordType uint16 // records returned
RequestType uint16 // where these results came from (TypeA, TypeAAAA etc)
}
Results holds results of a lookup
