Simple GeoIP and ASNnum query server http://ip.yooooo.us
  • nginx with ngx_http_geoip_module, echo-nginx-module, lua-nginx-module is required; libgeoip needs to be installed and geoip database should be placed under /usr/share/GeoIP.
  • http://example.com for current GeoIP and http://example.com/ip for current IP only
  • http://example.com/x.x.x.x to query any IP.
  • http://example.com/domain-name for GeoIP of domain-name and http://example.com/domain-name/ip to return IP of domain-name only. If multiple IPs are set to single domain-name, all of them will be returned. Only A record will be used.
  • Sample requests are:
$ curl http://example.com/
x.x.x.x
Country, Region, City
ASN number

$ curl http://example.com/ip
x.x.x.x

$ curl http://example.com/rdns
x.x.x.x.com

$ curl http://example.com/74.125.203.199
74.125.203.199  th-in-f199.1e100.net
United States, California, Mountain View
AS15169 Google Inc.

$ curl http://example.com/www.google.com.hk
74.125.203.199  th-in-f199.1e100.net
United States, California, Mountain View
AS15169 Google Inc.

$ curl http://example.com/www.google.com.hk/ip
74.125.203.199

$ curl http://example.com/www.google.com.hk/dns
