Class C IP Checker
Class C IP Checker
Paste a list of domains, URLs or IP addresses and see which Class C block (×.y.z.0/24) each one resolves into — hosts landing in the same block are grouped and flagged, so you can spot shared hosting footprints and link neighborhoods.
- Prepare domains
- Resolve DNS records
- Group Class C blocks
203.0.113.7 → 203.0.113.0/24). Blocks holding two or more of your domains are reported as overlaps; private/reserved ranges (10/8, 192.168/16, 127/8…) are marked. Results can shift with round-robin DNS — nothing is saved.How to use Class C IP Checker
