Read implements the net.Conn read method.

ReadMsg reads a message from the connection co. If the received message contains a TSIG record the transaction signature is verified. This method alwa

Remove creates a dynamic update packet deletes RR from a RRSset, see RFC 2136 section 2.5.4 See [ANY] on how to make RRs without rdata.

SetAxfr creates message for requesting an AXFR.

SetRcode creates an error message suitable for the request.

SetTsig appends a TSIG RR to the message. This is only a skeleton TSIG RR that is added as the last RR in the additional section. The TSIG is calculat

Verify validates an RRSet with the signature and key. This is only the cryptographic test, the signature validity period must be checked separately. T

Helper function for packing and unpacking

parseDstFromOOB takes oob data and returns the destination IP.

stringToTTL parses things like 2w, 2m, etc, and returns the time in seconds.

Extract the rr number from TYPExxx

unpackRRslice unpacks msg[off:] into an []RR. If we cannot unpack the whole array, then it will return nil

ActivateAndServe starts a nameserver with the PacketConn or Listener configured in *Server. Its main use is to start a server from systemd.

CertificateToDANE converts a certificate to a hex string as used in the TLSA or SMIMEA records.

ClientConfigFromReader works like ClientConfigFromFile but takes an io.Reader as argument

IsRRset reports whether a set of RRs is a valid RRset as defined by RFC 2181. This means the RRs need to have the same type, name, and class.

NameList returns all of the names that should be queried based on the config. It is based off of go's net/dns name building, but it does not check the

SetIncludeFS provides an [fs.FS] to use when looking for the target of $INCLUDE directives. ($INCLUDE must still be enabled separately by calling [Zo

SetUDPSize sets the UDP buffer size.

Unpack unpacks a binary message to a Msg structure.

makeSVCBKeyValue returns an SVCBKeyValue struct with the key or nil for reserved keys.

packBufferWithCompressionMap packs a Msg, using the given buffer buf.

parse parses an RR from zone file format. This will only be called on a new and empty RR type with only the header populated.

Parse LOC records' <digits>[.<digits>][mM] into a mantissa exponent format. Token should contain the entire string (i.e. no spaces allowed)

typeBitMapLen is a helper function which computes the "maximum" length of a the NSEC Type BitMap field.

ClientConfigFromFile parses a resolv.conf(5) like file and returns a *ClientConfig.

Dial connects to the address on the named network.

Hijack lets the caller take over the connection. After a call to Hijack(), the DNS package will not do anything with the connection.

IsDomainName checks if s is a valid domain name, it returns the number of labels and true, when a domain name is valid. Note that non fully qualified

Out performs an outgoing transfer with the client connecting in w. Basic use pattern: ch := make(chan *dns.Envelope) tr := new(dns.Transfer) var w

ReadPrivateKey reads a private key from the io.Reader q. The string file is only used in error reporting. The public key must be known, because some c

RemoteAddr returns the net.Addr of the client that sent the current request.

SetExtendedRcode sets the EDNS extended RCODE field. If the RCODE is not an extended RCODE, will reset the extended RCODE field to 0.

TrimDomainName trims origin from s if s is a subdomain. This function will never return "", but returns "@" instead (@ represents the apex domain).

TsigVerify verifies the TSIG on a message. If the signature does not validate the returned error contains the cause. If the signature is OK, the error
