ssh ipv6 offending host key and internet provider

My internet service provider gives me a new ipv6 range /56 about every 8 weeks.
Then I stumble over this

ssh user@some other host
Warning: the ECDSA host key for ' some other host' differs from the key for the IP address '1111:2222:3333:4444:5555:6666:7777:8888'

Offending key for IP in /home/xx/.ssh/known_hosts:8
Matching host key in /home/xx/.ssh/known_hosts:11
Are you sure you want to continue connecting (yes/no)?

I do not want keys based on IPv6 . Each host in my intranet has a proper name chez moi.
That should be the identification for the keys
How can I suppress this seemingly automatic host key generation from varying references?
