Brian,

thanks,
A new version is in preparation, I forgot that it was not yet published.
The remark of Michael, that coap discovery is an extension to GRASP
discovery is also valid.
In the text, a mention about Grasp discovery will be inserted, and a
reference to constrained coap networks to motivate the coap discovery.
And indeed copying IP addresses is not my best side.

Greetings,

Peter
