ip 주소로 국가 조회하는 방법 about.ip2c.org API

아이피주소로 국가 조회하기

서비스하는 내용이 국가별로 제한되는 부분이라

DB를 구축하자니 그 업데이트관리가 문제이고

API가 있지 않을까 해서 구글링을 통해 알게된 사이트입니다.

아래 내용은 about.ip2c.org 사이트에서 발췌한 INPUT/OUTPUT 설명입니다.

 

==== Accepted inputs: ============================================================

You can use http or https.

https://ip2c.org/XXX.XXX.XXX.XXX
or
https://ip2c.org/?ip=XXX.XXX.XXX.XXX
|
+ standard IPv4 from 0.0.0.0 to 255.255.255.255
+ e.g. we take your IP:
    |
    + URL looks like this:  https://ip2c.org/128.134.3.161
    |                       or
    |                       https://ip2c.org/?ip=128.134.3.161
    |
    + resulting string is:  1;KR;KOR;Korea Republic of


https://ip2c.org/XXXXXXXXXX
or
https://ip2c.org/?dec=XXXXXXXXXX
|
+ decimal number from 0 to 4294967295 (MAX_INT)
+ faster than ?ip= option, less server-side processing
+ to convert IPv4 to decimal you only need to know this:
    |
    + (IPv4) A.B.C.D == A*256^3 + B*256^2 + C*256 + D (decimal)
    + e.g.   5.6.7.8 == 5*256^3 + 6*256^2 + 7*256 + 8
                     == 5*16777216 + 6*65536 + 7*256 + 8
                     == 83886080 + 393216 + 1792 + 8
                     == 84281096


https://ip2c.org/s
or
https://ip2c.org/self
or
https://ip2c.org/?self
|
+ processes caller's IP
+ faster than ?dec= option but limited to one purpose - give info about yourself


Caution
Some clients (e.g. ASP) may have issues while trying to open a file over HTTP.
In that case a slash / preceding ?ip= is obligatory.

==== Possible outputs: ===========================================================

You can use http or https.

0;;;WRONG INPUT
|
+ your request has not been processed due to invalid syntax
    |
    + e.g. bad IPv4 like 300.400.abc.256
    + e.g. bad decimal like 2a3b4c or bigger than MAX_INT


1;CD;COD;COUNTRY
|
+ contains two-letter (ISO 3166) and three-letter country codes, and a full country name
+ country name may be multi-word and contain spaces
+ e.g. we take your IP:
    |
    + URL looks like this:  https://ip2c.org/128.134.3.161
    |                       or
    |                       https://ip2c.org/?ip=128.134.3.161
    |
    + resulting string is:  1;KR;KOR;Korea Republic of


2;;;UNKNOWN
|
+ given ip/dec not found in database or not yet physically assigned to any country


The first digit indicates status so you don't have to always parse the whole string.
Output is always semicolon delimited text/plain - you can pass it to any type of application.
