This seems like it's probably legitimate. Does it need to be fixed in the -bis document?
-MSK ---------- Forwarded message --------- From: RFC Errata System <rfc-edi...@rfc-editor.org> Date: Sat, Mar 23, 2024 at 8:04 AM Subject: [Technical Errata Reported] RFC7489 (7865) To: <superu...@gmail.com>, <zwi...@yahoo-inc.com>, <rfc-...@rfc-editor.org> Cc: <fra...@frieder.es>, <rfc-edi...@rfc-editor.org> The following errata report has been submitted for RFC7489, "Domain-based Message Authentication, Reporting, and Conformance (DMARC)". -------------------------------------- You may review the report below and at: https://www.rfc-editor.org/errata/eid7865 -------------------------------------- Type: Technical Reported by: Fränz Friederes <fra...@frieder.es> Section: Appendix C Original Text ------------- <!-- Credit to Roger L. Costello for IPv4 regex http://mailman.ic.ac.uk/pipermail/xml-dev/1999-December/ 018018.html --> <!-- Credit to java2s.com for IPv6 regex http://www.java2s.com/Code/XML/XML-Schema/ IPv6addressesareeasiertodescribeusingasimpleregex.htm --> <xs:simpleType name="IPAddress"> <xs:restriction base="xs:string"> <xs:pattern value="((1?[0-9]?[0-9]|2[0-4][0-9]|25[0-5]).){3} (1?[0-9]?[0-9]|2[0-4][0-9]|25[0-5])| ([A-Fa-f0-9]{1,4}:){7}[A-Fa-f0-9]{1,4}"/> </xs:restriction> </xs:simpleType> Corrected Text -------------- <!-- Credit to Roger L. Costello for IPv4 regex http://mailman.ic.ac.uk/pipermail/xml-dev/1999-December/ 018050.html --> <!-- Credit to java2s.com for IPv6 regex http://www.java2s.com/Code/XML/XML-Schema/ IPv6addressesareeasiertodescribeusingasimpleregex.htm --> <xs:simpleType name="IPAddress"> <xs:restriction base="xs:string"> <xs:pattern value="((1?[0-9]?[0-9]|2[0-4][0-9]|25[0-5])\.){3} (1?[0-9]?[0-9]|2[0-4][0-9]|25[0-5])| ([A-Fa-f0-9]{1,4}:){7}[A-Fa-f0-9]{1,4}"/> </xs:restriction> </xs:simpleType> Notes ----- The IPv4 regex contains a period "." that should be corrected to an escaped period "\." As stated in the follow up message of the one referenced in the IPv4 regex credit: "I just realized that there is a bug [...] The period (.) is a special character meaning 'any character'. To indicate that we want a period and not 'any character' the period must be escaped with a backslash, i.e., \." Following the XML schema provided in the original Appendix C, strings like "1a1a1a1" and "1111111" are considered valid IPv4 addresses, although they are not usable.
