Functions

func Query4

func Query4(domain string) *dns.Msg

Query4 requests an A record answer

func Query6

func Query6(domain string) *dns.Msg

Query6 requests an AAAA record answer

func QueryPTR

func QueryPTR(ip string) *dns.Msg

QueryPTR retrievs reverse DNS records

func SmuggleError

func SmuggleError(err error) *dns.Msg

SmuggleError crafts a custom DNS answer to include our error message. This allows the function to only have one return, thus simplifying our pipeline. (maybe)

Types

type DNSMap

type DNSMap struct {
	IPToPTR   cmap.ConcurrentMap
	NameToIPs cmap.ConcurrentMap // map[string]*IPName
	// SeenIPs is a map of IP addresses that have been seen in the DNS query results
	// in theory this will be merged into an out of scope key/value store when the DNSMap is destroyed
	SeenIPs cmap.ConcurrentMap // map[string][]string
	Working *int64
	// contains filtered or unexported fields
}

DNSMap is used for resolving and keeping track of DNS query results and their relationships

func NewDNSMap

func NewDNSMap(name string) *DNSMap

NewDNSMap creates a new DNSMap type

type IPName

type IPName struct {
	Name string
	IPs  []string
}
