KOREA Government’s IPv6 StrategiesKOREA Government’s IPv6 Strategies
1. In the past Just supporting only IPv6 technologies and applications
projects through MIC+/NIA++
Depending upon only telco’s for IPv6 deployment over their commercial networks
2. 2005 ~ 2007 Interested in real IPv6 applications, contents, and users Formed IPv6 Deployment Promotion Council
3. NOW NIDA+++ is in charge of promoting IPv6 Interested in deploying IPv6 infrastructure at
government agencies in advance Make new strategy to promote IPv6 and its applications

IPv6 migration strategy in KTIPv6 migration strategy in KT
Phase Time Migration strategy
Preparation ~ 2008
Maintain current IPv4 network IPv6 Experiment / Trial Node Operation Enhance IPv6-based technologies /
network equipment function Make policy of IPv6 service and
educational programs
Transition ~ 2010
Install 6PE - IPv4/IPv6 operation in only PE nodes - IPv4 operation in VPN PE / partial node secure IPv6 operational know-how promote IPv6 user connectivity
Native IPv6 ~ 2013
Install Dual Stack step 1: Install Dual stack in core and
remove 6PE function step 2: IPv6 deployment in all core
network equipments

OverviewOverview
1. background Give IPv6 connectivity and experience to end users
who wants to use ipv6 application in person
2. Features Permanent global IPv6 address to end users over IPv4
Tunnel Permanent Domain name by dynamic DNS
－ djkwak.ktv6user.kr Personal web, mail, ftp, UCC server by domain name
－ http://djkwak.ktv6user.kr
－ mail.djkwak.ktv6user.kr Access the domain name by both IPv4/IPv6 network
