Known hosts and dynamic IP addresses

[Hadmut Danisch]

Hi,

it becomes more and more common to have machines with 
dynamically assigned  IP addresses online (e.g. DSL), which 
can be found through dynamic DNS entries.

Unfortunately, the "Known Hosts" mechanism doesn't work for 
these machines: Since the entry is made for the IP address,
there's a new entry every time the address changes.


Therefore, an option should be invented which allows to 
store the host key under the DNS name only.
