IpRev Result Codes - s.2.7.3

Variants

Unknown

Result code not seen

Pass

The DNS evaluation succeeded, i.e., the “reverse” and “forward” lookup results were returned and were in agreement.

Fail

The DNS evaluation failed. In particular, the “reverse” and “forward” lookups each produced results, but they were not in agreement, or the “forward” query completed but produced no result, e.g., a DNS RCODE of 3, commonly known as NXDOMAIN, or an RCODE of 0 (NOERROR) in a reply containing no answers, was returned.

TempError

The DNS evaluation could not be completed due to some error that is likely transient in nature, such as a temporary DNS error, e.g., a DNS RCODE of 2, commonly known as SERVFAIL, or other error condition resulted. A later attempt may produce a final result.

PermError

The DNS evaluation could not be completed because no PTR data are published for the connecting IP address, e.g., a DNS RCODE of 3, commonly known as NXDOMAIN, or an RCODE of 0 (NOERROR) in a reply containing no answers, was returned. This prevented completion of the evaluation. A later attempt is unlikely to produce a final result.

Trait Implementations

impl Clone for IpRevResultCode

fn clone(&self) -> IpRevResultCode

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for IpRevResultCode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for IpRevResultCode

Returns the “default value” for a type.

impl PartialEq for IpRevResultCode

fn eq(&self, other: &IpRevResultCode) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
