Is Dynu Dynamic DNS Client safe?

Low risk

Dynu Dynamic DNS Client reads your public IP address over HTTP before updating Dynu DNS records.

When the extension checks for IP address changes, it requests IPv4 and IPv6 address data from Dynu's IP-check endpoints over cleartext HTTP. It then sends the resulting address to Dynu's API along with stored Dynu account credentials so the DNS record can be updated.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.
