Batch PTR reverse lookup over an IPv4 CIDR block, grouped by naming pattern.
Find all public domains hosted on a given IPv4, aggregated and deduplicated across multiple sources.
Trace which IPs a domain has resolved to, or which domains have historically pointed at an IP, with first/last-seen windows. Note: for IP queries the results overlap heavily with Reverse IP, so this tool is better suited to domain lookups; for IP snapshots, use Reverse IP directly.
