the machine's external ip address static address. have until instance terminated or until amazon needs renumber network. months or years now, in day , age, static gets.

8.12. can use static ip address in instances?

no. image must configured dhcp client , assigned ip address.

this confused me little bit: http://developer.amazonwebservices.com/connect/entry.jspa?externalid=1346 --> introduction

elastic ip addresses static ip addresses designed dynamic cloud computing. elastic ip address associated account, not particular instance, , control address until choose explicitly release it. unlike traditional static ip addresses, however, elastic ip addresses allow mask instance or availability zone failures programmatically remapping public ip addresses instance associated account. rather waiting on data technician reconfigure or replace host, or waiting dns propagate of customers, amazon ec2 enables engineer around problems instance or software programmatically remapping elastic ip address replacement instance.

is there way machine instance can have static ip address linked it?

in aws-ec2 console can associate elastic ip. static ip dedicated you. when elastic ip not associate instance pay it.

no cost elastic ip addresses while in use

$0.01 per non-attached elastic ip address per complete hour

$0.00 per elastic ip address remap – first 100 remaps / month

$0.10 per elastic ip address remap – additional remap / month on 100

this ip can assign running ec2 instance.
