Per-instance Ethernet bandwidth is bounded by the NIC of the underlying instance type. No separate per-public-IP throttle occurs on top of that. Network speed for each instance type is listed in its specification table. See the [GPU instances](/platform/instances/gpu-instances) and [CPU instances](/platform/instances/cpu-instances) pages. Frontend bandwidth is provided on a shared, best-effort basis over high-bandwidth data-center and backbone networks, with Ethernet and DPU offload designed for near line-rate performance between Nodes and the edge. For high-bandwidth distributed workloads such as multi-Node training, use the dedicated [HPC interconnect](/products/networking/hpc-interconnect/about-hpc-interconnect) (InfiniBand or equivalent) rather than the standard Ethernet path.
