SMTP, Inc. Obtains a Significant Block of IP Addresses

SMTP Is Allocated 4,096 Portable IPv4 Addresses by ARIN

CAMBRIDGE, MA--(Marketwire - May 24, 2011) - SMTP, Inc. (OTCBB: SMTP), the global leader in email delivery services for permission-based marketing and transactional email, today announced that it has successfully obtained 4,096 portable virgin IPv4 addresses in a direct allocation from the American Agency for Internet Numbers (ARIN).

On February 3rd, 2011, the Internet Assigned Numbers Authority allocated the final remaining large blocks of IPv4 addresses to the regional registries, including ARIN in North America. On April 14th, 2011, the Asia/Pacific regional registry APNIC reached stage 3 address exhaustion, triggering a policy of limiting IP allocations to a hard maximum of 1,024 addresses. It is not known how much time is left before the North American IP pool is depleted, but industry experts feel it is a matter of time.

"The entire process for successfully delivering email through the Internet is dependent on IP addresses, and the associated reputation of those addresses for sending legitimate email that isn't spam," commented Semyon Dukach, Chairman and CEO of SMTP. "More and more of our customers are requesting their own dedicated IPs, while ISPs are experiencing a growing IP address shortage. As a result it has become critical for us to have direct control over a sufficient supply of IP addresses to accommodate our growth."

"IP reputation is the single most important factor in determining whether outbound email ends up in the inbox or in the spam folder," continued Dukach. "When a new IP is requested from an ISP it has often been used for sending email in the past, with dubious effects on its reputation. On the other hand, with this new direct allocation of 4,096 virgin IPs from ARIN, SMTP will be in a position to guarantee that our corporate customers can send their email over IPs never previously used by anyone else. In addition, only directly assigned portable IPs can be moved from one data center to another, assuring that our customers will never have to lose their earned IP reputation simply because we move our servers."

"For a company in the email delivery business like SMTP, adding a block of over four thousand clean and portable IP addresses that we directly control is a critically valuable asset in an environment of rapidly dwindling global supply," stated Richard Harrison, President of SMTP.

The next generation of IP address technology, known as IPv6, has an abundance of addresses for allocation to both ISPs and end-user companies. However, migration to IPv6 has been slow in developing and its impact when it comes to the email delivery and reputation process is still an unknown.

"IPv6 migration is eventually inevitable, but time frames and impact are still a little fuzzy. Until that story unfolds, we feel very comfortable that our customers will not be forced into a rushed technology migration before they are ready, due to the unavailability of IPv4 addresses," said Harrison.
