IPv6 Notation

IPv6 is the latest version of Internet Protocol (IP) that is suitable for large-scale IP networks. IPv6 supports a
128-bit address to allow 2
The IP address of the IPv6 host is always represented as eight groups of four hexadecimal digits separated by
colons. For example
abbreviated to compress one or more groups of zeroes or to compress leading or trailing zeroes.
The following examples show various representations of the address

IPv6 uses a "/" notation which describes the number of bits in netmask as in IPv4.
2001:db8::1/128 – Single Host
2001:db8::/64 – Network
IPv6 configuration is supported only on IAP-214/215, IAP-224/225, IAP-274/275, IAP-314/315, IAP-
324/325, and IAP-334/335 access points.

Enabling IPv6 Support for IAP Configuration

IAPs support IPv6 address mode for the following features:

SNTP Over IPv6

Supported IP modes
Instant supports two modes of IP address configuration:
V4-only—The IAP would allow IPv6 clients to pass-through just like the previous Instant release.
l
V4-prefer—Supports both IPv4 and IPv6 addresses. If the IAP gets both IPv4 and IPv6 responses for a DNS
l
query, then the IAP would prefer the IPv4 DNS address instead of the IPv6 DNS address.
