Functions

func ClientIP

func ClientIP(hdrs map[string][]string, hasCanonicalHeaders bool, remoteAddr string, monitoredHeaders []string) (remoteIP, clientIP netip.Addr)

ClientIP returns the first public IP address found in the given headers. If none is present, it returns the first valid IP address present, possibly being a local IP address. The remote address, when valid, is used as fallback when no IP address has been found at all.

func ClientIPTags

func ClientIPTags(remoteIP, clientIP netip.Addr) (tags map[string]string)

ClientIPTags returns the resulting Datadog span tags `http.client_ip` containing the client IP and `network.client.ip` containing the remote IP. The tags are present only if a valid ip address has been returned by ClientIP().
