Reverse IP Lookup — Domains on the Same IP
Reverse IP lookup: find other domains hosted on the same IP address. Useful for spotting shared-hosting neighbours, though results are never exhaustive.
A reverse IP lookup flips the usual question around. Instead of 'what IP does this domain use?', it asks 'which other domains are known to sit on this same IP?' On shared hosting, many sites live behind one address, and this tool surfaces the ones a lookup can identify.
Read the results honestly
The list reflects only what the lookup source has on record — it is a sample, not a complete census. Domains the source has never seen, or newly pointed ones, simply won't appear, and two different reverse-IP tools can legitimately return different overlapping lists.
It's also normal for a large site to return one neighbour or none: dedicated IPs and CDN edges map to a single site or to a shared network rather than a crowd of small sites.
Frequently asked questions
- Does sharing an IP with bad sites hurt my SEO?
- In almost all cases, no — search engines understand that shared hosting means unrelated sites share IPs. It only becomes a concern in extreme, deliberately abusive network setups, which ordinary shared hosting is not.
- Can I look up an IP directly?
- Yes. If you already have the IP, enter it and skip the domain-to-IP step. Otherwise a domain is resolved to an IP first, then reversed.
- Why so few results for a site I know is big?
- Big sites usually sit on dedicated IPs or behind a CDN, so the address maps to them alone or to a shared edge network — either way, a reverse lookup finds few or no other domains.
