i have 2 relays, configured with ipv4 adresses.

I have write to my isp and asked: can you change the ripe data ?

isp: no 

my: ok :-( , i can also not change the reverse dnsname

1. So the question: is that a god way to change the config from IP-adress to dnsname in the torrc.

2. Can i also set the hostname manualy ? On Atlas is that my isp.

So when there is coming a abuse, all contact is going first to my isp, and not to me.

3. Is that ok when i change the exit-html expl. with my email and business adress
