# Locally Unique Host #### The Basics A locally-unique host is a [FQDN](https://en.wikipedia.org/wiki/FQDN) defined by **you** and resolved only by you; similar to how a \[hosts file]\()) is implemented. Not to be confused with @canonically-unique-host. #### In-depth information You have the option to share your interpretation of how the host is resolved (e.g., `localhost` always resolves to `127.0.0.1`) but the resolution is not canonically enforced (e.g., someone else can map `localhost` to any arbitrary IP address). Hosts in a public subscription can be considered @canonically-unique-host's within the @I2P network but, ultimately, you are free to re-define them as you wish. #### Notes * Haven primarily uses @canonically-unique-host resolution while @I2P only uses @locally-unique-host resolution. * @I2P's and @Kovri's assigned top-level domain is currently `.i2p` and @Kovri intends to only process/use the `.i2p` [top-level domain](https://en.wikipedia.org/wiki/Top_level_domain) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://wiki.havenprotocol.org/overview/locally-unique-host.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
