 ** Ipv4 **   
The IPv4 address to assign to the endpoint network interface in the subnet. You must provide an IPv4 address if the VPC endpoint supports IPv4.  
If you specify an IPv4 address when modifying a VPC endpoint, we replace the existing endpoint network interface with a new endpoint network interface with this IP address. This process temporarily disconnects the subnet and the VPC endpoint.  
Type: String
