Ottawa, ON -- (SBWIRE) -- 06/16/2010 -- Roaring Penguin offers a DNS-based IPv6 Reputation List to qualified institutions running IPv6 based mail servers. As IPv6 adoption increases, inevitably spammers will begin transmitting spam via IPv6. Roaring Penguin's anti-spam products have been IPv6-ready since August 2009 and have been collecting IPv6 reputation data for many months. Roaring Penguin's President David Skoll remarked, "We are seeing IPv6 spam and signs of IPv6 botnets in the wild; any organization wishing to deploy IPv6 needs an IPv6-ready email security system."

Roaring Penguin Software's CanIt line of anti-spam solutions includes support for IPv6. It can accept and deliver mail via SMTP over IPv6 and perform rule lookups against IPv6 addresses and networks. In addition, all CanIt components can use IPv6 for intra-cluster communication.

David Skoll says, "The number of mail servers running IPv4 far exceeds the number running IPv6. For this reason, the IPv6 block list contains only a few hundred entries compared to over ten million in our IPv4 reputation list. Roaring Penguin expects the adoption of IPv6 to proceed at an ever accelerating rate as we exhaust the available IPv4 addresses. Our IPv6 list will automatically grow as IPv6 is more widely deployed."

IPv6 will become a "must-adopt" technology within Roaring Penguin's key client base of Universities, ISPs and MSPs. Hurricane Electric of Fremont California estimates that in less than 450 days we will have exhausted the available IPv4 central registry Internet addresses. A countdown counter is available at http://ipv6.he.net/statistics/.

About IPv6
IPv6 is short for "Internet Protocol Version 6". IPv6 is the "next generation" protocol designed by the Internet Engineering Task Force IETF to replace the current version Internet Protocol, IP Version 4 ("IPv4").

IPv6 fixes a number of problems in IPv4, such as the limited number of available IPv4 addresses. It also adds many improvements to IPv4 in areas such as routing and network autoconfiguration. IPv6 is expected to gradually replace IPv4, with the two coexisting for a number of years during a transition period.
