- ❗If you delete the default VPC, you can [recreate it via the CLI or the console](http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/default-vpc.html#create-default-vpc).
- ❗Be careful with VPC VPN credentials! If lost or compromised, the VPN endpoint must be deleted and recreated. See the instructions for [Replacing Compromised Credentials](http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_VPN.html#CompromisedCredentials).
- ❗Security Groups and Route Tables apply entries separately for IPv4 and IPv6, so one must ensure they add entries for both protocols accordingly.
- 💸Managed NAT gateways are a convenient alternative to
manually managing [NAT instances](https://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPCNATInstance.html), but they do come at a cost per gigabyte. Consider alternatives if you're transferring many terrabytes from private subnets to the internet.
