Ipv6AddressType	String	Non	Oui	Le type d'adresse IPv6 de l'instance ALB.	Valeurs valides : Internet : l'instance ALB utilise une adresse IPv6 publique. Le nom de domaine de l'instance ALB est résolu vers l'adresse IPv6 publique. Intranet : l'instance ALB utilise une adresse IPv6 privée. Le nom de domaine de l'instance ALB est résolu vers l'adresse IP privée.
