octodns.record.naptr

Classes

NaptrRecord(zone, name, data[, source, context])
NaptrValue(value)
NaptrValueBestPracticeValidator(id[, sets])	Checks that the NAPTR replacement field ends with a trailing . (fully-qualified name) when non-empty and not the null replacement ".".
NaptrValueRfcValidator(id[, sets])	Strict NAPTR rdata validator per RFC 3403 §4.1.
NaptrValueValidator(id[, sets])	Validates NAPTR rdata: order and preference are integer-parsable, flags is one of the RFC 3403 values, and service, regexp, and replacement are all present.

class octodns.record.naptr.NaptrValueValidator(id, sets=None)

Bases: ValueValidator

Validates NAPTR rdata: order and preference are integer-parsable, flags is one of the RFC 3403 values, and service, regexp, and replacement are all present.

validate(value_cls, data, _type)

Validate a record’s rdata values.

Parameters:

• value_cls (type) – The concrete value class being validated (e.g. MxValue, _Ipv4Value). Validators that need access to value class-level attributes (e.g. VALID_ALGORITHMS, _address_type) should read them from value_cls. Per-instance configuration should live on self, not on value_cls.

• data (list | tuple | str | dict) – The rdata to validate. For multi-value record types this is a list/tuple of value dicts or strings; for single-value types it may be a bare value. Most validators iterate data directly — when a validator needs to accept either form it should normalize with if not isinstance(data, (list, tuple)): data = (data,).

• _type (str) – The record type string (e.g. 'MX', 'A'). Passed through to helpers like _check_target_format which format it into their reason strings.

Returns:

A list of human-readable reason strings describing validation failures. Must return an empty list when the values are valid. Reasons from multiple validators are concatenated by the caller, so each reason must stand alone without context from the others.

Return type:

list[str]

Notes

Implementations must not raise on invalid input — all failures are reported via the returned list. Reason strings are surfaced verbatim in ValidationError messages, so phrasing and punctuation should be stable across releases.

class octodns.record.naptr.NaptrValueRfcValidator(id, sets=None)

Bases: ValueValidator

Strict NAPTR rdata validator per RFC 3403 §4.1.

• order and preference must be integers in [0, 65535] (uint16).

• flags must be one of S, A, U, P (case-insensitive) or empty.

• replacement must be a fully-qualified domain name (ending with ".") or "." for the null replacement.

Enabled as part of the strict validator set:

manager:
  enabled:
    - strict

_valid_flags = frozenset({'A', 'P', 'S', 'U'})

validate(value_cls, data, _type)

Parameters:

class octodns.record.naptr.NaptrValueBestPracticeValidator(id, sets=None)

Bases: ValueValidator

Checks that the NAPTR replacement field ends with a trailing . (fully-qualified name) when non-empty and not the null replacement ".".

Enabled as part of the best-practice validator set:

manager:
  enabled:
    - best-practice

validate(value_cls, data, _type)
