Reserved IPs

A reserved IP is an IP address kept for your account until you delete it. The Type column of the Manage Reserved IP list shows which of the two types it is.

A Public reserved IP is a static public address. You can point DNS at it, reach a resource at the same outside address every time, and move it to another resource when you need to fail over.

A VPC IP has the Type Private. It is a private IP reserved from a VPC in your E2E MyAccount project, which you attach to an instance or an inference service in TIR. To make a VPC there, see Create a VPC. The resource then talks to that VPC over private addresses only, away from the public internet.

The two types

	Public	VPC IP (Type Private)
Reserve it with	Reserve New IP	Reserve from VPC
What it is	A static public address	A private IP allocated inside the VPC you chose
Attach it to	An instance, a VM, a Slurm cluster, or a Kubernetes cluster	An instance or an inference service
How many a resource holds	One instance can hold several	An instance or an inference service holds one at a time
Transfer to another project	Yes	No; delete it and reserve a new one there
Billing	Charged monthly until you delete it	Free in TIR

Reserving a VPC IP takes two addresses from the VPC: the IP and an Egress IP. The list shows both, with the VPC under VPC Name. You can attach, detach, and delete either type.

How a public reserved IP differs from a default public IP

An instance gets a public IP by default. It keeps that IP through a restart, but a stop gives it back, so the next start can bring a different address. A reserved IP keeps its address through a stop and a start, because it stays reserved for you. See Manage IP addresses on an instance.

States

State	What it means
Reserved	The IP is allocated to your account and free to attach. The list shows Available.
Attached	The IP is assigned to a resource and traffic to it reaches that resource. The list shows Attached.
Detached	The IP is still allocated to your account and free to attach again. The list shows Available again.
Released	The IP is deleted and released from your account. It leaves the list.

The Manage Reserved IP list shows only Available and Attached, so a newly reserved IP and a detached one both read Available.

VPC IP connection status

After you attach a VPC IP, the status moves from Connecting to Connected, or to Connection Failed when the connection fails. Idle means the VPC IP is free to attach, which is how a newly reserved or a detached VPC IP reads.

Where the VPC comes from

You choose the VPC when you reserve a VPC IP, in My Account Region, My Account Project, and VPC. The region is fixed to match your TIR project: Delhi-NCR in Delhi, Chennai in Chennai. Choose a VPC that is Active and uses an address range E2E assigned; a VPC with a custom range is refused. You need MyAccount VPC permission to see the list of VPCs.

Networking > VPC is a different product: a VPC you create in TIR, with a range you choose, for a virtual machine on a CPU plan. A VPC IP comes only from a MyAccount VPC, so those are the only VPCs listed when you reserve one. A virtual machine on a CPU plan uses a VPC from the VPC page instead of a VPC IP. See VPCs.

Limits and billing

Your account can hold five reserved IPs in each region by default, counted across all of its projects, and E2E can raise the number. A public reserved IP is charged monthly until you delete it, even while it is Available, so delete the ones you have finished with. A VPC IP is free in TIR. See Reserved IP billing.

What you can do

Reserve an IP, attach it and detach it, transfer a public one to another project, or delete it.
