Overview

The IP Management module lets parent account administrators request, allocate, monitor, and configure dedicated IP addresses for their accounts and sub-accounts, directly from the platform UI.

Dedicated IPs improve email deliverability. They give you control over your sending reputation and flexibility in managing your infrastructure.

On the Email API CpaaS dashboard, navigate to Settings > Dedicated IP to open IP Management. The page has three tabs: IP address, IP pool, and Reverse DNS.

Pre-Requisites

Before you start, ensure you have:

• Completed billing setup. Netcore enables dedicated IPs only after billing is confirmed.
• A parent account. Sub-accounts can't request or manage IPs.
• DNS access to add A records and validate reverse DNS (rDNS).
• A volume forecast to determine the right number of IPs and a warm-up plan.

Dedicated IP Lifecycle

1. Request IPs

Request new dedicated IPs based on your sending volume and region requirements.

Key rules

• Only the parent account can request IPs.
• You can request a maximum of 50 IPs per request.
• Netcore supports the US, IND, and EU regions.

Steps

1. On the Email API CpaaS dashboard, navigate to Settings > Dedicated IP and click Request IP.
2. Fill in the request form:
   • Number of IPs you need.
   • Region where you want the IPs provisioned.
   • RDNS hostname for your dedicated IP. Select this from your approved sending domains. You can't use a domain outside your account. If you haven't added and verified a sending domain yet, add one first, then come back to request your IP.
3. Review the cost estimate shown in the form. Netcore charges you per IP, per month. New IPs ship with auto-warmup enabled by default.
4. Click Review request, confirm the details, and click Submit request. You agree to recurring billing for the IPs when you submit.

What happens next

1. You get a receipt email right away. Since dedicated IPs are billed on a recurring monthly basis, you agree to this when you submit the request, so there's no separate confirmation step to complete afterward.
2. Netcore reviews your request. During this stage, the status shows as Pending (action: Awaiting review) on the IP requests page. You'll get another email once your request is approved. If Netcore rejects it, the reason is shown against the request.

2. Track Your Requests

Click View requests on the Dedicated IP page to open the IP requests page.

An IP request shows one of three top-level statuses. Once a request is Approved, it also shows a sub-status that tracks your DNS setup progress.

Statuses

Sub-statuses under Approved

3. Verify the A Record

Once your request status changes to Approved, map the RDNS hostname to your dedicated IP in your DNS. Until you start, the request shows the Not configured sub-status with a Set RDNS action; once you begin, it shows Pending.

Steps

1. On the IP requests page, click Set RDNS or Verify A record against the approved request.
2. The DNS records to add window lists every hostname with its type (A) and IP address. Use the copy icon next to each value, or click Export DNS to download all records.
3. Add the A records at your DNS provider (for example, GoDaddy, Cloudflare, or AWS Route 53). Point each hostname to its IP address.
4. Once the records propagate, return to this window. Verified records show a Verified status. If a record shows Address Not Verified, fix the record at your DNS provider and click Reverify.

4. PTR Configuration

Once all A records are verified, the sub-status changes to Processing, and the action shows PTR Setup in Progress.

Netcore configures the PTR record for your dedicated IP. This usually takes up to 12 hours, and often finishes sooner. The system checks the PTR automatically at regular intervals, so you don't need to take any action.

Once the PTR is validated, the sub-status changes to Active, and the IP appears under the IP address tab.

5. Manage Your IPs

Open the IP address tab to see all your dedicated IPs, along with their status (Active or Warming), region, pool count, sub-account count, auto-warmup state, and created date. Use the search box and the region filter to find a specific IP.

Click the three-dot menu next to an IP for the following actions:

Set as Primary / Remove from Primary

Mark an IP as a primary delivery IP for your account. You can mark more than one IP as primary. Any new sub-account you create automatically uses your primary IP(s) for sending, though you can change this per sub-account later from Sub-account Settings. If no IP is marked primary, delivery for the master account and any new sub-accounts falls back to Netcore's shared IPs. You can remove the primary status from an IP at any time.

Disable Auto-warmup

New IPs ship with auto-warmup enabled by default. Auto-warmup gradually ramps up sending volume on the IP based on delivery signals. Disable it if you want to manage warm-up yourself.

Manage IP

Assign the IP to sub-accounts and pools.

• Sub-accounts tab: Select up to 10 sub-accounts at a time that can send through this IP, then click Save.
• IP Pool tab: Select up to 25 pools at a time to add this IP to, then click Save.

View Performance

Opens the Insights section for this IP. See Monitor IP and Pool Performance.

6. Create and Manage IP Pools

Open the IP pool tab to create and manage pools. Pools group IPs from the same region, and you can assign them to sub-accounts. Use pools to separate email streams, for example marketing and transactional traffic.

Create a pool

1. Open the IP pool tab and click Create pool.
2. Enter a pool name, select the region, and select the IPs to include.
3. Click Create pool.

Rules

• Each pool can contain up to 100 IPs.
• A pool must always contain at least one IP.
• Pool names must be unique, and can use only letters, numbers, hyphens, and underscores, up to 50 characters.
• A pool can't mix IPs from different regions. You can't change the region after you create the pool.

Pool actions

Click the three-dot menu against a pool:

• Assign subaccount: Select up to 10 sub-accounts per request that can send through this pool, then click Save. You can edit the selection anytime.
• Edit: Change the pool name, or add and remove IPs using the checkboxes.

7. Manage Reverse DNS

Open the Reverse DNS tab to see every IP, along with its verification status, region, RDNS hostname, and assigned users.

Netcore configures a default RDNS for each IP during the request process. You can change it later, for example to use your customer's or sender's domain as the dedicated RDNS.

Edit an RDNS

1. Click the edit icon against the IP.
2. Step 1: Review the current PTR for the IP.
3. Step 2: Select the new sending domain from your approved sending domains. Netcore automatically generates the subdomain and shows the resulting hostname, for example d180-141-smtp-out-us.test98.cpaasqa.site for the sending domain cpaasqa.site. You can't enter a custom subdomain, and you can't use a domain that isn't an approved sending domain on your account.
4. Step 3: Add the A record shown in the window at your DNS provider, pointing the new hostname to the IP. Use Export DNS to download the record.
5. Click Save. Once the A record is published, PTR configuration starts automatically.

8. Allocate IPs from Sub-account Settings

You can also manage a sub-account's allocation from Settings > Subaccounts > Edit > Account settings.

The current allocation (IPs or pool, with region) appears at the top and applies to every sending domain under the sub-account.

Under Change allocation, choose the allocation type: IP address (multi-select) or IP pool. Add or remove IPs, or select a pool, then click Save.

Rules

• You can assign a sub-account multiple IPs and multiple pools.
• If you remove the current allocation entirely, Netcore moves the sub-account to the shared IP pool.
• You can't remove the last dedicated IP without the sub-account falling back to shared IPs. Review this before you save.

Monitor IP and Pool Performance

Navigate to Insights > IP Insights to review performance.

1. Select IP Address or IP Pool from the selector.
2. Select the IP or pool, and the duration (for example, last 14 days).
3. Review delivered, bounced, complaints, opens, clicks, and spam score, along with the delivery trend, health score, blacklist status, and recommendations.

Best Practices

• Keep IP pools region-specific. Don't mix US, EU, and IND IPs in one pool.
• Separate marketing and transactional traffic across different pools.
• Configure SPF, DKIM, and DMARC, in addition to rDNS, for complete domain authentication.
• Plan migrations carefully. Assigning dedicated IPs removes shared IPs from sub-accounts.
• Keep auto-warmup enabled unless you already have your own warm-up plan ready. You can't turn it back on once you disable it.
• Review IP health and Insights regularly, especially during and after warm-up.
• Watch for the receipt email after you submit a request, and the follow-up email once it's approved.
