Information About IPv6 HTTP(S)
Cisco IPv6 Embedded Management Components
Cisco embedded management components have IPv6-compliant operability in IPv6 and dual-stack IPv6 and IPv4 networks.
HTTP(S) IPv6 Support
This feature allows the HTTP(S) client and server to support IPv6 addresses.
The HTTP server in Cisco software can service requests from both IPv6 and IPv4 HTTP clients. When the HTTP(S) server accepts a connection from a client, the server determines whether the client is an IPv4 or IPv6 host. The address family, IPv4 or IPv6, for the accept socket call is then chosen accordingly. The listening socket continues to listen for both IPv4 and IPv6 connections.
The HTTP client in Cisco software can send requests to both IPv4 and IPv6 HTTP servers.
When you use the IPv6 HTTP client, URLs with literal IPv6 addresses must be formatted using the rules listed in RFC 2732.
How to Configure IPv6 HTTP(S)
Disabling HTTP Access to an IPv6 Device
HTTP access over IPv6 is automatically enabled if an HTTP server is enabled and the device has an IPv6 address. If the HTTP server is not required, it should be disabled.
