[rancid] @ip -> names

[Isma]

Hi,

We use rancid  for some months now.
In the beginning, we have used ip adresses of switches we monitored like this
(routers.db)

192.168.50.107:cisco:up
192.168.50.108:cisco:up
192.168.50.109:cisco:up
192.168.50.110:cisco:up

now I want to use :

switch1:cisco:up
switch2:cisco:up
switch3:cisco:up
switch4:cisco:up

Now, I want to use their names

What do I have to do to keep all the revisions ?

Thanks in advance.
