1 Generation of Unique Domain Name based on Network Device Identifier Jae-Hoon Jeong, Jung-Soo Park, Hyoung-Jun Kim ETRI 19 th Nov th IETF – Atlanta, Georgia, USA draft-jeong-name-generation-00.txt

2 Problem In the current DNS, –Given domain, domain name is selected by a user. –The uniqueness of domain name should be verified by network manager. This naming is difficult to adopt in Un-administrated Networks, –SOHO, Home-network and Ad-hoc network, –where there are no network manager and dedicated name server.

3 Mechanism to automate the generation of unique domain name Network Device Identifier EUI64-ID User-IDDomain Unique Domain Name

5 Pros and Cons Pros –Automatically generated domain name Not need name allocation server –Uniqueness of domain name is guaranteed w/o additional verification procedure. Cons –A little User-unfriendly name by EUI-64 ID However, this naming can be useful to network devices in zero-configuration networks
