Custom VPS Request

As @jasonjpeters said, your OS, RAM and disk requirements can be met by our standard droplet plans. You can review the plans here.

Each droplet comes with 1 public ipv4 address and you can also add:

• 16 ipv6 addresses free if selected on the create page but we do block all SMTP on ipv6

We also offer floating IPs which can be assigned to your droplet but I do not believe these can be used for SMTP either.

Hello,

Each new droplet comes with a dedicated IP address. The droplet can have one IPv4 address, but we can also issue up to 16 IPv6 addresses per droplet. You can read more about IPv6 here: https://www.digitalocean.com/docs/networking/ipv6/

Another thing to mention is the usage of a Floating IPs.

A Floating IP is an IP address that can be instantly moved from one Droplet to another Droplet in the same datacenter.

Part of a highly available infrastructure is being able to immediately point an IP address to a redundant server. This is now possible with the addition of Floating IPs.

Floating IPs are free to use. However, due to the shortage of IPv4 addresses available, if you reserve an address but don’t assign it to a Droplet, we charge $0.006 per hour for each unassigned, reserved IP. (You can relinquish unused IPs from the control panel.) To keep billing simple, you will not be charged unless you accrue $1 or more.

Hope that this helps! Regards, Alex
