@IP-question Sky uses a pool of several milion IP4 addresses which are assigned to customers as you connect to Sky severs. Therefore while an occasional address can be blacklisted by providers for producing spam if this is happening regularly to you I would chheck the devices on your network as one could be compromised and being used to generate spam,
A decent malware scanning app like Malware Bytes can usually fix this kind of issue. Powering down your hub for at least an hour should get you a fresh IP address.
