This plugin adds a new report to your Matomo showing which Internet Service Providers your visitors used to access your website. You can click on a provider name for more details. If Matomo can't determine a visitor's provider, it is listed as IP.
Add the following to config/config.ini.php to change the plugin behaviour:
[Provider]
; Whether to skip the DNS reverse lookup when the configured location provider (eg an ISP or
; ASN database) doesn't return any ISP or organisation information for a visitor's IP.
; The lookup is a blocking, uncached DNS request performed within the tracking request, and can
; add several seconds to it whenever no PTR record exists or the resolver is slow to answer.
; Set to 0 to perform the lookup anyway, at the cost of slower tracking requests.
