Add IP address spaces

Updated

emnify is rolling out a new Custom IP address space feature to extend the available IP address spaces and eliminate the current /24 and /28 limitations.

What are the current IP address space limitations?

The /24 and /28 spaces have limited available IP addresses.

A /24 space provides 256 IP addresses. However, the first and last IP addresses are reserved for network and broadcast addresses, respectively, leaving 254 usable IP addresses for devices. Likewise, a /28 space provides 16 IP addresses, 14 of which are usable for devices.

With this new feature, organizations are assigned /16 IP address spaces by default. A /16 space provides 65,534 usable IP addresses, so by introducing and making this the default, emnify significantly extends the available IP addresses for your devices.

With this feature, your organization can:

• Retain any already allocated IP address spaces.
• Allocate new IP address spaces from shared (RFC6598 100.64.0.0/10) and the private (RFC1918) address spaces as follows:
  • Private ranges available to device IP addresses are 10.192.0.0/12, 10.112.0.0/12, 10.176.0.0/12, 10.56.0.0/13, 10.136.0.0/13, 10.208.0.0/13, and 10.224.0.0/13.
  • Any shared range is available except 100.64.0.0/24.

By default, you're assigned /16 IP address spaces in 100.64.0.0/10 (RFC6598) and don't need to configure it explicitly.

warning

You can't allocate overlapping IP address spaces, for example, 10.176.0.0/12 and 10.176.0.0/24 or 10.188.33.16/28.

To add a new IP address space, log in to your emnify account and follow these steps:

1. Navigate to Device Policies and go to IP Address Space Management.
2. Click Add new IP address space to open the modal.
3. In the IP Address Space field, enter the range you want to allocate. The field contains a provided network prefix by default, but you can customize it.
4. Review and click Apply.

Once added, you can see the count of IP addresses allocated to your devices and the number of available IPs in the space.

note

The status reads Not in use until an IP is assigned. Once assigned, the status changes to Assigned to devices. You can't edit or remove the IP address space if your devices use it.

Remove an IP address space

To remove an IP address space, disassociate all IP addresses from your devices. Then, follow these instructions:

1. Find the space you no longer need in the IP Address Space Management section.
2. Click Delete.
