5.135.48.50is one of such IP addresses. It has as abuse-c abuse@for-ns.com, which is trivially invalid: for- ns.com mail is handled by 10 mail.for-ns.com. mail.for-ns.com has address 176.9.154.142 Yet, there is no mail server on 176.9.154.142:25
Port 43 access provides:
% Information related to '5.135.48.48 - 5.135.48.51'
% Abuse contact for '5.135.48.48 - 5.135.48.51' is 'abuse@for-ns.com' % Abuse-mailbox validation failed. Please refer to ORG-OS3-RIPE for further information.
I am unable to see such piece of information on the RDAP view, though: https://rdap.db.ripe.net/ip/5.135.48.48
You are correct: the RIPE RDAP service returns the abuse-c contact as an entity under an IP object, but not the "validation failed" comment. We will add this comment as a "remarks" data structure within the IP object: https://tools.ietf.org/html/rfc7483#section-4.3 We plan to work on the RDAP functionality after the RIPE 80 meeting, we will include this change. Thanks for bring this omission to our attention. Regards Ed Shryane RIPE NCC
