	11	## Install
	12
	13	```sh
	14	$ npm inst all proxy- addr
	15	```
	16
	17	## API
	18
	19	```js
	20	var proxya ddr = requ ire('proxy -addr')
	21	```
	22
	23	### proxya ddr(req, t rust)
	24
	25	Return the address o f the requ est, using the given `trust` p arameter.
	26
	27	The `trust ` argument is a func tion that returns `t rue` if yo u trust
	28	the addres s, `false` if you do n't. The c losest unt rusted add ress is
	29	returned.
	30
	31	```js
	32	proxyaddr( req, funct ion(addr){ return ad dr === '12 7.0.0.1' } )
	33	proxyaddr( req, funct ion(addr, i){ return i < 1 })
	34	```
	35
	36	The `trust ` arugment may also be a singl e IP addre ss string or an
	37	array of t rusted add resses, as plain IP addresses, CIDR-form atted
	38	strings, o r IP/netma sk strings .
	39
	40	```js
	41	proxyaddr( req, '127. 0.0.1')
	42	proxyaddr( req, ['127 .0.0.0/8', '10.0.0.0 /8'])
	43	proxyaddr( req, ['127 .0.0.0/255 .0.0.0', ' 192.168.0. 0/255.255. 0.0'])
	44	```
	45
	46	This modul e also sup ports IPv6 . Your IPv 6 addresse s will be normalized
	47	automatica lly (i.e. `fe80::00e d:1` equal s `fe80:0: 0:0:0:0:ed :1`).
	48
	49	```js
	50	proxyaddr( req, '::1' )
	51	proxyaddr( req, ['::1 /128', 'fe 80::/10'])
	52	proxyaddr( req, ['fe8 0::/ffc0:: '])
	53	```
	54
	55	This modul e will aut omatically work with IPv4-mapp ed IPv6 ad dresses
	56	as well to support n ode.js in IPv6-only mode. This means tha t you do
	57	not have t o specify both `::ff ff:a00:1` and ` IP `.
	58
	59	As a conve nience, th is module also takes certain p re-defined names
	60	in additio n to IP ad dresses, w hich expan d into IP addresses:
	61
	62	```js
	63	proxyaddr( req, 'loop back')
	64	proxyaddr( req, ['loo pback', 'f c00:ac:1ab 5:fff::1/6 4'])
	65	```
	66
	67	* `loopb ack`: IPv4 and IPv6 loopback a ddresses ( like `::1` and
	68	`127.0 .0.1`).
	69	* `linkl ocal`: IPv 4 and IPv6 link-loca l addresse s (like
	70	`fe80: :1:1:1:1` and `169.2 54.0.1`).
	71	* `uniqu elocal`: I Pv4 privat e addresse s and IPv6 unique-lo cal
	72	addres ses (like `fc00:ac:1 ab5:fff::1 ` and `192 .168.0.1`) .
	73
	74	When `trus t` is spec ified as a function, it will b e called f or each
	75	address to determine if it is a trusted address. T he functio n is
	76	given two arguments: `addr` an d `i`, whe re `addr` is a strin g of
	77	the addres s to check and `i` i s a number that repr esents the distance
	78	from the s ocket addr ess.
	79
	80	### proxya ddr.all(re q, [trust] )
	81
	82	Return all the addre sses of th e request, optionall y stopping at the
	83	first untr usted. Thi s array is ordered f rom closes t to furth est
	84	(i.e. `arr [0] === re q.connecti on.remoteA ddress`).
	85
	86	```js
	87	proxyaddr. all(req)
	88	```
	89
	90	The option al `trust` argument takes the same argum ents as `t rust`
	91	does in `p roxyaddr(r eq, trust) `.
	92
	93	```js
	94	proxyaddr. all(req, ' loopback')
	95	```
	96
	97	### proxya ddr.compil e(val)
	98
	99	Compiles a rgument `v al` into a `trust` f unction. T his functi on takes
	100	the same a rguments a s `trust` does in `p roxyaddr(r eq, trust) ` and
	101	returns a function s uitable fo r `proxyad dr(req, tr ust)`.
	102
	103	```js
	104	var trust = proxyadd r.compile( 'localhost ')
	105	var addr = proxyadd r(req, tru st)
	106	```
	107
	108	This funct ion is mea nt to be o ptimized f or use aga inst every request.
	109	It is reco mmend to c ompile a t rust funct ion up-fro nt for the trusted
	110	configurat ion and pa ss that to `proxyadd r(req, tru st)` for e ach reques t.
