You misunderstood me. I'm not advocating de-registration of IP resources. I meant to remove just the abuse-c email address, since it does not work. As an alternative, as Àngel noted, there could be a tag saying that the email address is not valid, without actually removing it.
[Jordi] I got your point now, thanks!
I think it is more useful instead of removing the address, marking the record as invalid, and this is being done if I recall correctly from RIPE NCC presentations.
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.
