Four hostnames, each resolving to a pair of IP addresses: ns1052.ui-dns.biz directs to 185.132.33.52 and 2607:f1c0:fe:53:185:132:33:52; ns1052.ui-dns.com directs to 185.132.34.52 and 2607:f1c0:fe:53:185:132:34:52; ns1052.ui-dns.de directs to 185.132.32.52 and 2607:f1c0:fe:53:185:132:32:52; ns1052.ui-dns.org directs to 185.132.35.52 and 2607:f1c0:fe:53:185:132:35:52.
