A dedicated IP is an account-level outbound sending IP for SMTP mailboxes. Use dedicated IPs when you want reputation isolation, more control over sender routing, or a stable IP for selected domains.Documentation Index

What is a dedicated IP?
A dedicated IP is used for outbound SMTP traffic from the domains assigned to it. Assignment affects how Hybridbox routes mail for those domains. Dedicated IPs are useful when you want to separate reputation from shared infrastructure, route specific domains through specific IPs, or keep a stable sending IP for production mail. Dedicated IPs are managed at the account level. After an IP is available in the account, assign domains to route mail through it.Add a managed dedicated IP
Managed dedicated IPs come from the Hybridbox pool. The Dedicated IPs page shows whether the account can claim another managed IP and which options are available. To add one, open Dedicated IPs, select an available managed option, claim it into the account, then assign the domains that should send through it. Availability depends on the account, plan, current inventory, and per-billing-period claim limits. If no managed IP is available, the claim action is disabled or the page explains why another IP cannot be claimed.Rotate a dedicated IP
There are two common rotation patterns. Release first, then claim another IP: remove or review the current domain assignments, release the old IP, claim a new IP, then assign the domains to the new IP. Claim an additional IP first: claim a new IP while keeping the old one active, move domains to the new IP, confirm routing and reputation indicators, then release the old IP.Install a dedicated IP on your own server
Hybridbox can also use a dedicated IP installed on your own server, sometimes called a bring-your-own-host or self-hosted proxy setup. This option must be enabled by support before it appears in the normal workflow. After support enables the option, open Dedicated IPs, copy the install command shown on the page, and run it on the server that will host the dedicated IP. Return to the page after installation and approve or authorize the new IP when it appears. The page may also let you reissue the authorization command if setup needs to be restarted.Assign domains
Assign active dedicated IPs to the domains that should route mail through them. Assignment changes can affect outbound mail routing immediately, so use active, healthy IPs and review reputation indicators before moving production traffic. Use View domains when you only need to inspect which domains are assigned. Use Assign domains when you need to change the assignment.Remove a dedicated IP
Removing a dedicated IP releases a managed IP from the account or deletes a self-hosted IP entry from the account view. Before removing an IP, review assigned domains, move or unassign anything that still depends on it, and confirm that no current sending workflow needs it.Roles
