Module `Dns.Soa`Source

Start of authority

The start of authority (SOA) is a resource record at domain boundaries. It contains metadata (serial number, refresh interval, hostmaster) of the domain.

Sourcetype t = {

nameserver : [ `raw ] Domain_name.t;
hostmaster : [ `raw ] Domain_name.t;
serial : int32;
refresh : int32;
retry : int32;
expiry : int32;
minimum : int32;

}

The type of a start of authority.

val create : 
  ?serial:int32 ->
  ?refresh:int32 ->
  ?retry:int32 ->
  ?expiry:int32 ->
  ?minimum:int32 ->
  ?hostmaster:'a Domain_name.t ->
  'b Domain_name.t ->
  t

create ~serial ~refresh ~retry ~expiry ~minimum ~hostmaster nameserver returns a start of authority. The default for hostmaster is replacing the first domain name part of nameserver with "hostmaster" (to result in hostmaster@foo.com if ns1.foo.com is the nameserver.

Sourceval pp : t Fmt.t

pp ppf t pretty-prints the start of authority.

Sourceval compare : t -> t -> int

compare a b compare all fields of a with b.

Sourceval newer : old:t -> t -> bool

newer ~old new checks if the serial of old is smaller than new. To accomodate wraparounds, the formula used is new - old > 0.
