Hostname Lookup
Resolve a public hostname into normalized, deduplicated IPv4 and IPv6 addresses.
Resolve a hostname
Hostname lookup versus DNS lookup
This tool answers the common question “which public IP addresses does this hostname resolve to?” It combines and deduplicates address results rather than exposing every DNS record type.
For mail routing, name servers, verification text, aliases and zone authority, use the more detailed DNS Lookup. DNS answers can vary over time due to TTL-based caching and traffic distribution.
Why non-public answers are rejected
WhatWebSees does not disclose or connect to internal destinations. If any resolved candidate is private, loopback, link-local, reserved or otherwise non-global, the whole lookup fails closed.
What this result means
These are the current public address candidates returned to this resolver. Multiple answers are normal for redundancy or traffic steering; an address answer does not prove an application is listening.
