Hi Paul,
You are a really technical guy, most shared hosting probably will not work for you, and you will be able to put in use this info:
there is a dc in Kansas, USA that offers really great prices to older generation dedicated servers.. and, I am talking about $20, $25 and $30 per server with at least 4 cores and 16Gb of ram + 1gbps line.
And, most servers over $20 come with 5 ipv4 addresses. So far, so good
Cons: you can't install your ubuntu, centos or other on these > you would need to open a support ticket. And, they do 1 free OS setup per month.
check these out:

I'm playing with them to see what is what - so far all good.
scr:
note: don't get hooked on 'instant setup'

.. order Monday - Friday and wait for them to set it up for you.

if you ever get tempted to go for Contabo vpss > be aware, ALL their IPs are blacklisted and 1/2+ of your emails will not get delivered.

maybe this helps
Best wishes,

p.s. if you like the 20i that we offer, I could open the 20i US offer at HostMaria for you (isn't being offered at the moment).
