Everything worth knowing, in one place.
WHAT IT IS
An IP address used solely by your account rather than shared with others on the server.
WHEN IT IS WORTH BUYING
A third party requires a fixed unshared address for whitelisting You send meaningful volumes of mail and want reputation you control A compliance requirement explicitly names a dedicated address An application genuinely needs its own address
WHEN IT IS NOT
For SSL. AutoSSL works on shared IPs. For SEO. No effect. For speed. No effect. Because it sounds better. Visitors never see it.
IF YOU ORDER ONE
Update your domain's A record, in whichever system hosts your DNS Re-run AutoSSL Request reverse DNS if you send mail Update SPF if it names an address Supply the address to any third party and confirm the integration works Record everywhere the address has been given
IF YOUR ACCOUNT IS EVER MIGRATED
The address changes. Work through the same list again.
IF UNSURE
Describe the requirement in a ticket. We will tell you honestly whether this solves it.
