FOR IMMEDIATE RELEASE

IANA Accepts SixChat End2End Direct Messaging Protocol (IRP)
Internet Assigned Numbers Authority assigns port 4605 to SixChat Protocol
The Internet Assigned Numbers Authority (IANA) officially assigned port 4605 to the SixChat End2End
Direct secure messaging protocol created by Sixscape Communications, Pte. Ltd. The assignment wasissued by IANA on 11th September, 2014, and is listed in the official IANA resource registry at
http://www.iana.org/assignments/service-names-port-numbers
There are a very limited number of port numbers, which are assigned by IANA for protocols recognized
as viable, complying with current protocol design standards, and not already covered by existing
Internet standards. For example, port 25 was assigned to the SMTP email protocol many years ago. This
provides a standard port and reduces conflicts with other protocols. The technical review of the SixChat
protocol was performed by Lars Eggert, the distinguished chair of the Internet Research Task Force.
The SixChat messaging protocol was created by Lawrence E. Hughes, co-founder and CTO of SixscapeCommunications, for their SixChat Internet application software. The new protocol allows two SixChat
User Agents to connect directly, perform mutual authentication with X.509 client digital certificates andthen securely exchange a symmetric session key (for encryption of all content). SixChat uses thecompany’s Identity Registration Protocol (IANA assigned port 4604) for address registry and retrieval, as
well as Public Key Infrastructure functions (to obtain and use client digital certificates).
Mr. Hughes commented “SixChat is one of the first, if not the first, application to truly leverage the IPv6Internet’s amazing new capabilities, including an essentially unlimited number of public addresses. We
are no longer bound by the constraints of Network Address Translation made necessary on the IPv4
Internet since 1995, due to address space depletion.”“SixChat is the pioneer App to show case the proper use of the e2e model for everyone” - Latif Ladid,
founder and President of worldwide IPv6 ForumThe Internet Assigned Numbers Authority (IANA) is responsible for the global coordination of the DNS
Root, IP addressing, and other Internet protocol resources, such as port numbers. More information isavailable at www.iana.org.
Lawrence E. Hughes is a 40+ year veteran of many Internet companies and is a recognized authority inIPv6 and Public Key Infrastructure. IPv6 is the latest version of the fundamental protocol underlying
Internet communications, and is being deployed worldwide now. By 2017, Internet traffic over IPv6 is
expected to surpass traffic over the older IPv4 in volume. Public Key Infrastructure involves issuing andmanaging X.509 digital certificates. Mr. Hughes created the original training in cryptography and PKI for
VeriSign (the leading company in PKI) from 1998-2000.

Sixscape Communications, Pte. Ltd. is a Singapore based company that creates and sells Internetapplications that feature strong support for IPv6 and Public Key Infrastructure (PKI). They are doing
pioneering work in the area of End2End Direct secure communications, made possible by IPv6. Moreinformation is available at www.sixscape.com.
