ipv6 host

Use this command to define static host name-to-IPv6 address mapping in the host cache. The parameter name is host name and v6 address is the IPv6 address of the host. The host name can include 1–255 alphanumeric characters, periods, hyphens, and spaces. Hostnames that include one or more space must be enclosed in quotation marks, for example “lab-pc 45”.
