APLRecordValidator

class APLRecordValidator implements DnsRecordValidatorInterface (View source)

Validator for APL (Address Prefix List) DNS records

Validates APL records according to RFC 3123: https://tools.ietf.org/html/rfc3123

APL RR type has a value of 42 and is used for lists of address prefixes, primarily for network access control or description purposes.

Format: [!]afi:address/prefix [!]afi:address/prefix ...

Where:

  • ! (optional): Negation symbol
  • afi: Address Family Identifier (1 for IPv4, 2 for IPv6)
  • address: Network address in appropriate format (IPv4 dotted quad or IPv6 notation)
  • prefix: Prefix length (0-32 for IPv4, 0-128 for IPv6)

Multiple address prefix items can be listed, separated by whitespace. An empty APL RR is valid and represents an empty list.

Examples:

  • "1:192.0.2.0/24" (IPv4 subnet)
  • "2:2001:db8::/32" (IPv6 subnet)
  • "!1:192.0.2.0/24 2:2001:db8::/32" (Negated IPv4 subnet plus IPv6 subnet)
