IPv6
IPv6 uses 128-bit addresses. A portal offered over it needs matching DNS, network, server and access-rule configuration.
What does IPv6 mean?
IPv6 is the version of the Internet Protocol developed as IPv4's successor. RFC8200 describes, among other changes, the address space expanded to 128 bits. RFC4291 explains how addresses are assigned to network interfaces and written using colons. An interface can have several IPv6 addresses.
Example: also offering the portal over IPv6
In a fictional design, a portal already reachable over IPv4 is to support IPv6 as well. An AAAA record publishes an IPv6 address for the portal name. The record does not configure the network route, access rules or web service.
The team checks actual access over IPv6 separately. A working IPv4 connection does not demonstrate that reachability. Services in front of the portal and monitoring must also fit the connection being offered.
The protocol version does not decide permissions within the portal. Login and project permissions still apply in the application; IPv6 replaces neither these rules nor protection of the application data being transmitted.

- IP addressAn IP address provides addressing on a network. It differs from a domain name and alone says nothing about the application reachable at that address.
- AAAA recordAn AAAA record maps a DNS name to an IPv6 address. Suitable network and server configuration is needed to make the service reachable through it.
- IPv4IPv4 addresses network destinations using 32-bit addresses. A DNS record and a reachable address do not replace configuring and checking the service.
- Return-PathReturn-Path records the SMTP reverse path in a header. It explains the technical route for error reports, not a person’s identity.
- Envelope-FromEnvelope-From identifies the SMTP sender for transport and error feedback. It must be distinguished from the visible sender address.
- DMARC aggregate reportA DMARC aggregate report summarises a reporting mail system’s domain checks over a period. It helps examine sending sources and misconfigurations.
