Wrong IP address in config.php, trusted domains? -->ripe.net<--

while I looked in my new Nextcloudpi (Debian 10, Nextcloud 20.0.11) I found ja IP address (config.php, trusted domains) which I don’t know:

11 => ‘’,

who.is says, it belongs to:
OrgName: RIPE Network Coordination Centre
Address: P.O. Box 10096
City: Amsterdam
PostalCode: 1001EB
Country: NL
Updated: 2013-07-29
Ref: https://rdap.arin.net/registry/entity/RIPE

Does anybody know why this address is in my “config.php” under trusted domains?

Myip.ms says:

IP Reverse DNS (Host): dyndsl-188-118-162-225.ewe-ip-backbone.de.
Maybe this is your ISP?

Nevertheless, if you don’t know about that IP address it’s advised to check your server for signs of intrusion, especially around SSH. For more information you should tell us more about the kind of installation of your Nextcloud, the hoster (if hosted somewhere) etc.
