I get the same result when I query 1.1.1.1 or 1.0.0.1 for archive.is:

    ┌
    └─(12:32:59)──> nslookup archive.is 1.1.1.1 
                                            
    Server:  1.1.1.1
    Address: 1.1.1.1#53

    Non-authoritative answer:
    Name: archive.is
    Address: 89.253.237.217

    ┌
    └─(12:38:12)──> nslookup archive.is 1.0.0.1
                                            
    Server:  1.0.0.1
    Address: 1.0.0.1#53

    Non-authoritative answer:
    Name: archive.is
    Address: 89.253.237.217

Wonder why that is happening...
