Background & Need

IPv4 DNS

IPv6 DNS

Need for systematic

.KR DNS and tech.

for early settlement of

local IPv6 DNS service

the importance of DNS protocol is increased under Internet environment, DNS tech. is advanced

Advent of IPv4 (Early 1980s)

Activated IPv4

(1990s)

Advent of IPv6

(1999)

Depletion of IPv4

(1994)

  • Activated hi-speed Internet service
  • Development of wireless/mobile tech.
  • Appearance of various new services
  • Advent of ubiquitous era
  • Arrangement for hi- performance IPv6 application test basis
  • Need for stable IPv6 DNS tech.
  • Increased Network/Host
  • Development of various application services
  • Early stage of Internet
  • Name-IP mapping table (hosts.txt file)
  • Needs for DNS

International Trend (1/6)

Worldwide Root DNS Servers : Total 13

slide31

International Trend (2/6)

IPv6 Compatibility with Root DNS

  • IPv4/IPv6 dual-interface on 5 root servers from perspective of IP layer- IPv6 based DNS Query acceptable- so, local server needs to be built up as dual network
  • IPv6 delegation to name servers under root- IPv6 AAAA delegation to ccTLD level name server (July 20, 2004 UTC)- Technical limit of DNS packet size 512 bytes

International Trend (5/6)

Dual-stack Status of ccTLD Countries

slide35

International Trend (6/6)

DNS Name System Simplification of ccTLD Countries

 Minimizing DNS response message size through consistent domain name

- Systemized domain name can be processed in compressed type

- This allows DNS response message size that is limited to 512 bytes

- This is also very sensitive factor in construction of dual-stack network and IPv6 delegation to root domain name server in the future
