# About networking

> Overview of CoreWeave networking products, including VPCs, HPC Interconnect, Direct Connect, IP addresses, and Ingress

CoreWeave offers a suite of networking products for managing network infrastructure. Our networking products are designed to create a secure, high-performance, and scalable network that interconnects your resources and services. This page introduces each product and links to more detailed documentation so you can choose the right ones for your workloads.

## Virtual private clouds

[Virtual Private Clouds](/products/networking/vpc/about-vpcs) (<Tooltip tip="A Virtual Private Cloud (VPC) is a private network hosted within a public cloud infrastructure." cta="Learn more" href="/glossary#virtual-private-cloud-vpc">VPCs</Tooltip>) are isolated networks used by CoreWeave Kubernetes Service (CKS) clusters to securely communicate with each other and the internet while maintaining privacy and security by defining the network isolation for attached CoreWeave products.

VPCs allow for the creation of segregated and secure networks for your resources within the CoreWeave Cloud infrastructure. This isolation ensures that your data and applications remain private and protected. VPCs are essential for organizations using cloud computing while maintaining strict control over network environments.

## HPC Interconnect

[HPC Interconnect](/products/networking/hpc-interconnect/about-hpc-interconnect) provides high-performance, RDMA-enabled fabrics for GPU-to-GPU communication. CoreWeave offers two distinct fabrics: NVIDIA Quantum InfiniBand and NVIDIA Spectrum-X (RoCE). Both are optimized for the high throughput and low latency required for large-scale model training and other demanding parallel workloads.

GPUDirect RDMA enables direct access between the main memory of two computers without involving the operating system, cache, or storage, which reduces latency and increases throughput.

## Direct Connect

[Direct Connect](/products/networking/direct-connect/about-direct-connect) lets you connect directly to CoreWeave through private, dedicated links. If you use Equinix or Megaport, you can use your existing connections when establishing direct connections to CoreWeave. You don't need to add additional dedicated physical ports or establish a network presence in our regions.

## IP addresses

CoreWeave supports both [Public IPv4](/products/networking/ip/public-ipv4) addresses and [Bring Your Own IP (BYOIP)](/products/networking/ip/bring-your-own-ip). Public IPv4 addresses ensure that your Services are accessible over the internet, which is necessary for deploying web applications and Services that need to be available globally. BYOIP lets you use your own <Tooltip tip="Internet Protocol version 4 (IPv4) is one of the core protocols that enables the internet." cta="Learn more" href="/glossary#internet-protocol-version-4-ipv4">IPv4</Tooltip> addresses on CoreWeave Cloud, which is useful for customers who have existing IP address spaces they want to use for workloads on CoreWeave.

## Ingress Service

The [Ingress Service](/products/networking/ingress-service/expose-service-dns) exposes Services running on CKS to the public internet using `LoadBalancer` Services and public IPv4 addresses. You can also [request a fully qualified domain name (FQDN) or wildcard record](/products/networking/ingress-service/create-public-dns-name) to provide a stable, human-readable address for your publicly exposed Services.
