+
+Determine address of proxied request
+
+## Install
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install proxy-addr
+```
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var proxyaddr = require('proxy-addr')
+```
+
+### proxyaddr(req, trust)
+
+Return the address of the request, using the given `trust` parameter.
+
+The `trust` argument is a function that returns `true` if you trust
+the address, `false` if you don't. The closest untrusted address is
+returned.
+
+<!-- eslint-disable no-undef -->
+
+```js
+proxyaddr(req, function (addr) { return addr === '127.0.0.1' })
+proxyaddr(req, function (addr, i) { return i < 1 })
+```
+
+The `trust` arugment may also be a single IP address string or an
+array of trusted addresses, as plain IP addresses, CIDR-formatted
+strings, or IP/netmask strings.
+
+<!-- eslint-disable no-undef -->
+
+```js
+proxyaddr(req, '127.0.0.1')
+proxyaddr(req, ['127.0.0.0/8', '10.0.0.0/8'])
+proxyaddr(req, ['127.0.0.0/255.0.0.0', '192.168.0.0/255.255.0.0'])
+```
+
+This module also supports IPv6. Your IPv6 addresses will be normalized
+automatically (i.e. `fe80::00ed:1` equals `fe80:0:0:0:0:0:ed:1`).
+
+<!-- eslint-disable no-undef -->
+
+```js
+proxyaddr(req, '::1')
+proxyaddr(req, ['::1/128', 'fe80::/10'])
+```
+
+This module will automatically work with IPv4-mapped IPv6 addresses
+as well to support node.js in IPv6-only mode. This means that you do
+not have to specify both `::ffff:a00:1` and `10.0.0.1`.
+
+As a convenience, this module also takes certain pre-defined names
+in addition to IP addresses, which expand into IP addresses:
+
+<!-- eslint-disable no-undef -->
+
+```js
+proxyaddr(req, 'loopback')
+proxyaddr(req, ['loopback', 'fc00:ac:1ab5:fff::1/64'])
+```
+
+ * `loopback`: IPv4 and IPv6 loopback addresses (like `::1` and
+ `127.0.0.1`).
+ * `linklocal`: IPv4 and IPv6 link-local addresses (like
+ `fe80::1:1:1:1` and `169.254.0.1`).
+ * `uniquelocal`: IPv4 private addresses and IPv6 unique-local
+ addresses (like `fc00:ac:1ab5:fff::1` and `192.168.0.1`).
+
+When `trust` is specified as a function, it will be called for each
+address to determine if it is a trusted address. The function is
+given two arguments: `addr` and `i`, where `addr` is a string of
+the address to check and `i` is a number that represents the distance
+from the socket address.
+
+### proxyaddr.all(req, [trust])
+
+Return all the addresses of the request, optionally stopping at the
+first untrusted. This array is ordered from closest to furthest
+(i.e. `arr[0] === req.connection.remoteAddress`).
+
+<!-- eslint-disable no-undef -->
+
+```js
+proxyaddr.all(req)
+```
+
+The optional `trust` argument takes the same arguments as `trust`
+does in `proxyaddr(req, trust)`.
+
+<!-- eslint-disable no-undef -->
+
+```js
+proxyaddr.all(req, 'loopback')
+```
+
+### proxyaddr.compile(val)
+
+Compiles argument `val` into a `trust` function. This function takes
+the same arguments as `trust` does in `proxyaddr(req, trust)` and
+returns a function suitable for `proxyaddr(req, trust)`.
+
+<!-- eslint-disable no-undef, no-unused-vars -->
+
+```js
+var trust = proxyaddr.compile('localhost')
+var addr = proxyaddr(req, trust)
+```
+
+This function is meant to be optimized for use against every request.
+It is recommend to compile a trust function up-front for the trusted
+configuration and pass that to `proxyaddr(req, trust)` for each request.
