# ASN targeting

ASN targeting is not compatible with any random continent, therefore the examples will vary from other targeting methods. This is because ASN targeting only uses region-based endpoints.

use one of these region endpoints depending on ASN:

* America: proxy-america.goproxies.com:1080
* Europe: proxy-europe.goproxies.com:1080
* Asia: proxy-asia.goproxies.com:1080

Format for username: customer-USERNAME-asn-XXXX (replace XXXX with the ASN).

Below are short snippet examples. Please see their comments too where applicable:

# Europe
curl --proxytunnel --proxy "https://customer-USERNAME-asn-54321:PASSWORD@proxy-europe.goproxies.com:1080" https://ip.goproxies.com

# Asia
