What is my IP address?

CLI examples

$ curl {{ .Host }}
{{ .IP }}

$ http -b {{ .Host }}
{{ .IP }}

$ wget -qO- {{ .Host }}
{{ .IP }}

$ fetch -qo- https://{{ .Host }}
{{ .IP }}

$ bat -print=b {{ .Host }}/ip
{{ .IP }}

{{ if .Country }}

Country lookup

$ http {{ .Host }}/country
{{ .Country }}

$ http {{ .Host }}/country-iso
{{ .CountryISO }}

{{ end }} {{ if .City }}

City lookup

$ http {{ .Host }}/city
{{ .City }}

{{ end }} {{ if .ASN }}

ASN lookup

$ http ip.alphakilo.eu/asn
{{ .ASN }}
{{ if .ASNOrg }}

Looks like you're with {{ .ASNOrg }}

{{ end }} {{ end }}

JSON output

$ http {{ .Host }}/json
{{ .JSON }}

Setting the Accept: application/json header also works as expected.

Plain output

Always returns the IP address including a trailing newline, regardless of user agent.

$ http {{ .Host }}/ip
{{ .IP }}

{{ if .Port }}

Port testing

$ http {{ .Host }}/port/8080
{
  "ip": "{{ .IP }}",
  "port": 8080,
  "reachable": false
}

{{ end }}

FAQ

How do I force IPv4 or IPv6 lookup?
