Managing Dedicated IPs

After your dedicated IPs arrive, you manage them under Setup → Dedicated IPs. Each IP's Action menu holds its settings, and the Status switch turns it on and off. Grouping IPs into pools is covered in Dedicated Pools.

Reverse DNS (rDNS)

Reverse DNS, also called a PTR record, is the hostname a receiving mail server gets back when it looks up your IP. Mailbox providers check that it's there and that it points back to the same IP. Every dedicated IP comes with a working hostname. You can ask for one on your own domain instead, for example mail1.example.com, so the IP carries your brand.

rDNS changes are enabled per account

The Edit DNS option only appears when reverse DNS changes are enabled on your account. If you don't see it, contact support.

Before you start

• The IP must be in a Dedicated Pool. If it isn't, you'll see "You need to assign this IP to a Dedicated Pool before you can request the Reverse DNS change." See Assigning IPs to a pool.

• Create the forward record first. Add an A record for the new hostname that points to the IP, at the DNS provider for your domain:

  mail1.example.com.   A   203.0.113.10

  Wait for the record to propagate before you save the change. Mumara ONE only accepts a hostname that resolves back to the IP.

• The hostname must be new. It has to differ from the IP's current hostname.

Changing the hostname

1. Go to Setup → Dedicated IPs.
2. In the IP's Action menu, choose Edit DNS. The Edit Reverse DNS dialog shows the IP Address and its Current RDNS.
3. Enter the hostname in New RDNS. The table below it shows the A record the hostname needs: Host, type A and the Ip Address. Use the copy icon to copy the IP.
4. Once the A record is in place, tick I confirm that I have created the Forward DNS record, then click Save.
5. Mumara ONE looks up the hostname:
   • If it resolves to the IP, you'll see "The new RDNS record has been successfully matched with the FDNS record."
   • If it doesn't, you'll see "The new rDNS record isn't forward confirmed. Please add a forward DNS record first." Check the A record, wait for DNS to update, and try again.
6. The IP's DNS Status changes to Modified, and a yellow bar at the top of the page asks you to send your changes for approval. Click Send for Approval to submit them, or Discard Changes to drop them.
7. After you send them, DNS Status shows Under Review. Our team reviews the change and applies it. If a change is declined, it's removed and the IP keeps its current hostname.

Change several IPs at once

Changes wait as Modified until you send them. You can edit several IPs, then send them all with a single Send for Approval.

DNS Status values

Value	Meaning
Confirmed	The IP's hostname and its forward DNS record match.
Unconfirmed	The hostname and forward DNS record don't match yet.
Modified	You saved a reverse DNS change but haven't sent it for approval.
Under Review	You sent the change, and our team is reviewing it.

Enabling and disabling an IP

The Status column has a switch for each IP.

• Off: the IP stops sending. The other enabled IPs in its pool carry the pool's traffic.
• On: the IP goes back into its pool's rotation.

Switching an IP off is useful when you want to rest it, for example while you look into a blocklist listing or a drop in its IP Health score.

The change is applied in the background. While it runs, Active Processes shows a message such as "The IP address 203.0.113.10 is being disabled." See Tracking changes in Active Processes.

The switch is unavailable when:

• the IP isn't in a pool yet
• a removal request is open for the IP
• another change to the IP is still being applied

Keep at least one IP enabled

If you switch off every IP in a pool, the pool has nothing to send from. Campaigns and Bridges that use that pool can't send until you switch an IP back on.

Open and click tracking

Open and click tracking isn't set for individual IPs. For transactional email, each Bridge has its own Track Opens and Track Clicks switches. See Bridges.

Tracking only works when your sending domain has its tracking domain enabled and configured. See Sending Domains.

Bulk operations

Bulk Operations makes the same change to many IPs, Bridges or pools at once.

Bulk operations are enabled per account

The Bulk Operations button only appears on Setup → Dedicated IPs when bulk operations are enabled on your account. If you need them, contact support.

1. Go to Setup → Dedicated IPs and click Bulk Operations.
2. Under Select Operation, choose what to do.
3. To narrow the list to one zone, pick it in the Select Server filter. Leave it on All to see everything.
4. Tick the rows you want. The checkbox in the header selects them all.
5. Click the operation's button.

Operation	What it does
Assign IPs	Lists your unassigned IPs. Click Assign, pick a pool in the Assign Pool dialog, and click Assign.
Unassign IPs	Lists IPs that are in a pool, with the pool's name. Click Unassign and confirm. The IPs stay on your account as Unassigned.
Update Reverse DNS	Lists your IPs with their hostnames. Type the new hostname in a row and click the arrow next to it to check it. Repeat for each IP, then use Send for Approval or Discard Changes. The same rules apply as for single changes. This option only appears when reverse DNS changes are enabled on your account.
Delete IPs	Lists your unassigned IPs. Click Delete to request their removal. Our team reviews the request, as for a single IP.
Bridges Delete	Lists your Bridges and their pools. Click Delete and confirm.
Pools Delete	Lists pools that have no IPs. Click Delete and confirm.

A progress bar shows how far the operation has got.

Assign within one zone

A pool only accepts IPs from its own zone. Before you assign several IPs at once, filter the list to a single zone with Select Server. That way the pool you choose fits every IP you selected.

Deleting Bridges is immediate

Bridges Delete removes the selected Bridges straight away, and you can't undo it. Any application that sends through them stops authenticating. Move those applications to other Bridges first.

Tracking changes in Active Processes

Changes to pools and IPs are applied on the sending servers in the background. You don't have to stay on the page while they run. This covers:

• creating and deleting pools
• assigning, unassigning and reassigning IPs
• enabling and disabling IPs

While a change runs:

• In the top bar, a gear icon appears. Click it to open Active Processes, which lists each change with a count. Each entry says what's happening, for example "The IP 203.0.113.10 is being assigned to the dedicated pool marketing.", and shows when it started.
• On the page, a spinning gear replaces the row's Action menu, with the tooltip "Assignment is under process." or "Request is under process."

When a change finishes, its entry shows a green check and "Operation completed successfully." If it fails, the entry shows a red warning and the reason.

How long changes take

Changes are usually picked up within about a minute, and most finish within a few minutes. Two limits stop a change from hanging:

• 60 seconds: if the sending servers don't answer within 60 seconds, the change fails, and the message says so.
• 10 minutes: a change that hasn't finished within 10 minutes is cancelled, with the message "The request was not completed within 10 minutes and has been terminated. Please try again."

After a failure, the row's Action menu comes back, and you can repeat the change. If a change keeps failing, contact support.

Reverse DNS changes and IP removal requests don't appear in Active Processes. They go through review instead, as described above.
