Currently, the following services are available:
1. Http://www.myipneighbors.com/, with a verification code, no other way to query restricted;
2. Http://www.iwebtool.com/reverse_ip. if you do not have a registration status, you can check the status for 5 times;
3. Http://whosonmyserver.com/, the unlimitedly used discountedscriptscode, or you can use discountedscripts demos to query;
4. Http://www.domaintools.com/reverse-ip/. for a finite query, you can provide the number and the first three domain names;
5. The ip-domain interface is consistent with the Interface 1. It is estimated that the same program or clone is used;
6. webhosting info,
7. yougetsignal,
