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