Unable to see my website

I have purchased a domain name from https://my.freenom.com and hosted the website from https://infinityfree.net. It was working all fine till 11/10/2018. But now it is not working anymore. Now, https://my.freenom.com says that “In order to use Freenom DNS, please set your nameservers to default (Freenom Nameservers)”. I did the same but now i don’t know what is the Name, A record, TTL, Target. Also want to know what all records i need to update in order to run my website? Please help.

How to find the IP address of your account

Don’t use Freenom’s DNS, use our DNS. Unless you know how to manage your own nameservers, but that risk is all yours.
