ip地址查询网站-ifconfig.co的源码

A simple service for looking up your IP address. This is the code that powers https://ifconfig.co

(another demo website: https://ip.gs)

Usage

Just the business, please:

$ curl ifconfig.co
127.0.0.1

$ http ifconfig.co
127.0.0.1

$ wget -qO- ifconfig.co
127.0.0.1

$ fetch -qo- https://ifconfig.co
127.0.0.1

$ bat -print=b ifconfig.co/ip
127.0.0.1

Country and city lookup:

$ curl ifconfig.co/country
Elbonia

$ curl ifconfig.co/country-iso
EB

$ curl ifconfig.co/city
Bornyasherk

$ curl ifconfig.co/asn
AS59795

As JSON:

$ curl -H 'Accept: application/json' ifconfig.co  # or curl ifconfig.co/json
{
  "city": "Bornyasherk",
  "country": "Elbonia",
  "country_iso": "EB",
  "ip": "127.0.0.1",
  "ip_decimal": 2130706433,
  "asn": "AS59795",
  "asn_org": "Hosting4Real"
}

Port testing:

$ curl ifconfig.co/port/80
{
  "ip": "127.0.0.1",
  "port": 80,
  "reachable": false
}

Pass the appropriate flag (usually -4 and -6) to your client to switch between IPv4 and IPv6 lookup.

Features

• Easy to remember domain name
• Fast
• Supports IPv6
• Supports HTTPS
• Supports common command-line clients (e.g. curl, httpie, wget and fetch)
• JSON output
• ASN, country and city lookup using the MaxMind GeoIP database
• Port testing
• Open source under the BSD 3-Clause license

Why?

• To scratch an itch
• An excuse to use Go for something
• Faster than ifconfig.me and has IPv6 support
