The question to pre sales is "are ip's available on different sub-nets for DNS resolution" (I was think on getting two servers"
"The /29 IP block are autoassigned from the available pool of IPs at the time your order is placed. You can request an additional IP block on the order form or in the web portal once your server is online."
I understand that. What I need to know is would the 2nd IP block be on a different subnet? An example would be say Googles DNS servers. 8.8.8.8 And 8.8.4.4 are different subnets. If the route to one fails, the other is available. Hope this better explains my question
The IPs are routed across two redundant paths. All IPs on our network are routed this way.
Not Buying, sorry,.

Maybe they mean their DNS servers are redundant or that their network is redundant, I would definitely ask for clarification on that. It does sound like they will only provide you IP's from the same subnet unless you order an additional /29 as you can't mix and match IP's on the same IP block.

I think that sales should have asked tech support before I became confused. I think that
"I understand that. What I need to know is would the 2nd IP block be on a different subnet?" should have given them a clue.
I read it as they have redundant networks, doesn't matter, I'm moving on.

Each /29 is a different subnet, that is the nature of the "/", if one bit is different before the / in the two / 29's it's a different subnet ( https://en.wikipedia.org/wiki/Classl...Domain_Routing )
They said there network has redundant paths. Maybe you want to ask them if you can get a server in a different location, or you'd prefer the networks not be contiguous. I don't see much reason for the latter, but you may want the former. Things like blacklists may block larger IP networks for email, so it would be good not to be "nearby".

Just as a general rule, when you order additional IPs at the same time as the server the additional IPs tend to be on the same block (i.e. a contiguous subnet). On the other hand, when you obtain IPs after buying the server it can go either direction if it's an automated system - either be an expansion of the current subnet or an entirely different one.
What you needed to ask for were two blocks on non-contiguous subnets. As to how "nearby" they are would really depend on the IP space the provider has available.

I can't confirm that, at OVH, Hetzner they weren't in the same /8. At myloc the additional IPs were on a different AS. The IPs were ordered directly after receiving the Server.
Maybe this works only at small Companys?

Well, when SoftLayer, Rackspace, LeaseWeb, Microsoft, Amazon, and Google are small companies although the last three are really cloud providers, we can consider that to be the case.
Until then, it seems budget companies like OVH and Hetzner seem to provides IPs defaulted in the way already described. I think that is where lies the problem, "budget providers."
Although don't get me wrong, get OVH with an enterprise contract and they will do very well. OVH with no enterprise commitment is a hit or miss.

Sales often doesn't know these answers. They're just generic q&a sorts
