Yes, it should be "nearly instant".
As Steve says, have a look at your switch ports first - I've been caught out with this in the past when using a managed switch that defaults to Spanning Tree turned on :( One very quick way round this is to attach your device to a really basic "dumb" switch.


Also, as a side note, unless you are part of Alascom, Inc, you shouldn't be using their IP allocation (12.12.0.0/17). You should stick to RFC1918 addresses (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16) which are explicitly set aside for private use. Even if this is a completely isolated network, it's bad practice to use someone elses addresses - one day you'll forget and it'll bite you on the backside.
