LGTM! Thanks.

There are limitations that make this impractical to currently write tests for

Basically the CNI bridge is responsible for handing out IP's
We could potentially create a test env, where the CNI bridge is groomed to already pass out larger IP's or something in the future.

Ignite has no current abililty to pre-define what that IP could be, but if that changes in the future, we would certainly want to test for this.

In general, the ignite-spawn sandbox process is under-tested at an individual level, but it is covered generally in the e2e tests.

Thanks for the reviews!
Super pleased to merge this fix

@stealthybox thanks so much! Any chance you could cut a release so we can try it out in our environment please?

@stealthybox @luxas sorry to bother you, but if you could release a version of ignite with this fix it, would be greatly appreciated! As we increase our usage of Ignite, we keep running into this more and more frequently. Thanks so much!
