Re: Request for Comments on Internet Draft about IoT DNS Name Autoconf

["Mr. Jaehoon Paul Jeong" <[e-mail]>]

Hi 6MAN colleagues,
I have changed the draft's name for the discussion in 6MAN WG:

https://tools.ietf.org/html/draft-jeong-6man-iot-dns-autoconf-00

I hope we can discuss how to configure the DNS names of IoT devices in
networks
(such as home network, enterprise network, road network, and factory
network)
with the minimum configuration effort.
Imagining that you have hundreds of IoT devices in your network,
will you configure their DNS names manually one by one?

To prepare for the new wave of IoT networks based on IPv6,
we need to think of the DNS naming for IoT devices.

Are there any thoughts or comments on this issue?

Thanks.

Paul
