Security Scan: which source ip to whitelist?

ℹ️ Support

Hi all,
I’d like to filter access to a Nextcloud instance by source ip.
I’d also like to be able to run security scans against my instance.
Is there an known list of IPV4/IPV6 source ip ranges to whitelist in order to allow https://scan.nextcloud.com to still reach my instance?

Thanks

I was successfully scanned by scan.nextcloud.com after creating a firewall rule on my router that allows incoming TCP packets from scan.nextcloud.com, which right now resolves to IP 95.217.53.149.
There was one time when this “trick” didn’t work, but it has worked the rest of the times. Try it and let us know!
