In this case we defaulted to trusting our customer and their LOA over a stranger on the Internet and asked our customer to review the request. Unfortunately, that doesn't necessarily mean a stranger on the Internet isn't the actual assignee. [......]
I believe the suggested process would be.... submit the stranger's request to the administrative & technical contacts listed for the organization and IP resource in public WHOIS at the time the request is received, and in order to confirm: Request whether their organization approves that the announcements must be withdrawn, and if so: that they also submit to you a signed official form to either revise, rescind, or repudiate the existing LOA provided by that WHOIS contact. Then reply to the "stranger" that official documentation is required to cancel the announcement, and you are unable to verify you have the right to make the request, and you will forward their message to the IP Address registry and officially listed WHOIS and customer technical contacts who must approve of the request, before any further actions can be taken. -- -JH
