ESP KingHost Blocked

[Giovani Zarpelon <giovani.zarpelon@xxxxxxxxxxxxxxx>]

Hi there!

My name is Giovani, I work on KingHost and I'm a member of the E-mail Infrastructure team.

We provide Internet Services, among them, we are an Email Service Provider (ESP) and we host tens of thousands of domains.

It seems to me that we have been blocked:

; <<>> DiG 9.11.36-RedHat-9.11.36-5.el8_7.2 <<>> 186.88.89.167.list.dnswl.org

If I use Google or Cloudflare DNS for example, the query works:

We actually make a lot of requests for you, but this is due to the volume of customers and processing that we have.

Please, I would like you to unblock the ranges below (our DNS):

177.12.169.0/24
2804:10:8254::/48

Thanks in advance,
