How to reserve an IP address?

Reserve IP address

You can reserve IP addresses from MyAccount . A Reserved IP address is a public IPv4 address. Reserving an IP address ensures that an IP address will be reserved for your MyAccount. This can be used for dynamic cloud computing and it is reachable from the internet.

You can use reserve IPs to create cloud server infrastructures without any single points of failure. With a reserved IP address, you can mask the failure of a resource due to increased system load or website by rapidly remapping the address to another instance in your MyAccount. Or, you can dynamically update the backend resources of your applications and websites by re-assigning the Reserve IP address with an insignificant downtime if at all.

For example, since DNS propagation takes time when A records of a domain name are changed, reserving an IP address allows you to re-assign the IP address to a new resource without updating your domain name A records; this is useful especially when you are moving to a different Node series — for example, C2 series to Smart Dedicated series.

The following are the basic characteristics of a Reserve IP address: To use a Reserve IP address for your MyAccount, you need to first reserve one IP either from an IP address pool or reserve your resource’s default public IPv4 address. Only after that, you can use it as an Add-On IP or Primary Public IP address. You can attach a reserve IP address as add-on IP with a resource, which is going to associate with the resource’s primary network interface and work as an additional IP address. Kindly note that resource’s primary public IPv4 static address will not be released back into E2E Networks’s pool of public IPv4 addresses after attaching additional addon Reserve IP.

You can also use a reserved IP address as the primary public IP address of a resource while creating a new Node/ Load Balancer.

Note

You will get a random static primary public IP for the newly created resource if you have not assigned a reserved IP as a primary public IP while creating a resource (node or load balancer).

There is an option available to change the default primary public IPv4 static address, which will work as the resource’s primary network interface. Kindly note that resource’s default primary public IPv4 address will be released back into E2E Networks’s pool of public IPv4 addresses when detached without reserving it.

You have the flexibility of detaching a Reserve IP address from a resource which is either used as add-on IP or primary public IP address of a resource and you can re-attach it to a different resource. The detached reserve IP address will remain reserved for your MyAccount until you explicitly release it.

Whenever you Reserve an IP address it will be billed at ₹199 (excluding GST) per calendar month whether it’s in use or not. If you are a prepaid customer, infra credits will be deducted as soon as an IP address is reserved. If you are a postpaid customer, the relevant charges will be added to your monthly invoice

To ensure efficient use of Reserve IP addresses, there is a default limit of reserve IP for your MyAccount. If your use case requires more IP, you may request for Increase IP Limit.
