# IPv6 Basic Technology
The main standard for IPv6 is [RFC 8200 ](https://www.rfc-editor.org/info/rfc8200 ). Many other relevant RFCs are cited in [IPv6 node requirements ](https://www.rfc-editor.org/info/bcp220 ). Quotes from relevant RFCs are included in this chapter.

Some generic terms that should be used precisely are given in Section 2 of RFC 8200. In particular:
- Node: a device that implements IPv6
- Router: a node that forwards IPv6 packets not explicitly addressed to itself
- Host: any node that is not a router
To avoid confusion, note that a router may receive and send its own packets, and run IPv6 applications, just as a host does.
The rest of this chapter covers various basic aspects of IPv6.
