Unfortunately, because of IPv4 exhaustion (the internet is effectively running out of IP addresses) we are unable to provide additional IP addresses to a managed server.
Generally speaking, dedicated or multiple IPs are no longer necessary from a technical standpoint (because of SNI in the case of SSL certificates on multiple websites) and also from a search engine optimization perspective, dedicated or multiple IP addresses are no longer relevant there either.
In addition we have decentralized our email system by relaying mail through SpamExperts and MailChannels. This way mail is delivered safely and reliably regardless of the web server IP address reputation.
If you have any further questions or concerns our support staff is available 24/7 to address them.
