public class Peer
extends software.amazon.jsii.JsiiObject

Peer object factories (to be used in Security Group management).

The static methods on this object can be used to create peer objects which represent a connection partner in Security Group rules.

Use this object if you need to represent connection partners using plain IP addresses, or a prefix list ID.

If you want to address a connection partner by Security Group, you can just use the Security Group (or the construct that contains a Security Group) directly, as it already implements IPeer.

Example:

 InstanceType instanceType;
 NatInstanceProvider provider = NatProvider.instance(NatInstanceProps.builder()
         .instanceType(instanceType)
         .defaultAllowedTraffic(NatTrafficDirection.OUTBOUND_ONLY)
         .build());
 Vpc.Builder.create(this, "TheVPC")
         .natGatewayProvider(provider)
         .build();
 provider.connections.allowFrom(Peer.ipv4("1.2.3.4/8"), Port.tcp(80));
