## Overview

A **host** is the address, port and SNI combination that goes into the links
your subscribers receive. It is deliberately separate from the inbound's real
binding, so what a client is told to connect to can differ from where the
listener actually sits, and that is how you point clients at a CDN, a second
domain, or a different port than the one Xray binds. Host templates let you
apply the same host configuration across many inbounds at once.

## Before you start

- You need inbounds configured first, because a host describes how clients reach one.
- Changing a host changes every subscription link generated from it, so expect
  clients to need a subscription refresh.

## Steps

1. Open **Server → Hosts** from the sidebar. The header shows how many hosts are
   configured.
2. Search or filter to find the hosts you want to work on.
3. Select several hosts to act on them together, so you can add a tag to all of
   them at once, or **Apply Template** to push a saved host configuration
   across the selection.
4. Open a host to edit its settings individually.
