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.

Node A paul MAC1 EUI-64.ADHOC

Node B paul MAC2 EUI-64.ADHOC

Node C paul MAC3 EUI-64.ADHOC

Factor of Uniqueness

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
