# VPC Peering Connections
VPC peering connection is a network connection between two VPCs. Through this connection, the instances in different VPCs can communicate with each other as if they are in the same network.
# Precautions
- EMQ X Cloud only supports creating peering connection at the same region.
- EMQ X Cloud does not accept CIDR in the range of 10.11.1.0/24 ~ 10.64.255.0/24.
- Peering connections are bound to resources. Please create peering connections before creating resources.
