AdminKit vs ViewDNS.info: reverse DNS (PTR) lookup
A live test of ViewDNS.info's Reverse DNS Lookup tool for a known IP (viewdns.info, read 2026-10-29) returned the correct PTR hostname but masked it as "xxx.xxxxxx" until signing in; AdminKit's reverse DNS tool shows the full PTR result with no account, though ViewDNS is part of a much wider 25+-tool site that AdminKit's single-purpose tool doesn't try to match.
What a live test actually showed
Running ViewDNS.info’s Reverse DNS Lookup tool against a known IP on 2026-10-29 returned the correct PTR hostname, but the page masked the displayed and exportable result as “xxx.xxxxxx,” with “Sign in to enable copy” and “Sign in to enable export” prompts next to it. The lookup itself runs without creating an account, but seeing the actual hostname without obscuring it appears to require signing in. AdminKit’s reverse DNS tool shows the full PTR hostname with no account at any point.
ViewDNS.info is not a single-purpose competitor: its own homepage lists roughly 25 tools — reverse IP lookup, Whois, DNS record lookup, port scanner and more — plus a documented API with its own pricing. AdminKit’s reverse DNS check is one tool in AdminKit’s own, smaller set of free network checks (DNS lookup, MX lookup, Whois/RDAP, subnet calculator and others), not a 25-tool platform.
The honest angle
This page isn’t claiming AdminKit matches ViewDNS.info’s breadth of tools or its API. The specific, sourced difference is narrower: for the one task both tools do — look up the PTR record for an IP — AdminKit shows the result in full for free, while ViewDNS.info’s web tool masked it behind a sign-in prompt at the time this was tested.
For the DNS record types a PTR lookup sits alongside, see AdminKit’s DNS lookup tool; for domain and IP registration data rather than hostnames, see how AdminKit’s Whois/RDAP tool compares to who.is.

Frequently asked questions
Does ViewDNS.info really hide the PTR result without an account?
Based on a live test of ViewDNS.info's own Reverse DNS Lookup tool for 8.8.8.8 on 2026-10-29, yes: the correct hostname was partially visible in the page but the displayed/exportable result was masked as "xxx.xxxxxx" with prompts to "Sign in to enable copy" and "Sign in to enable export." AdminKit's reverse DNS tool shows the full hostname with no account.
Does ViewDNS.info support IPv6 reverse lookups?
Unverified. The ViewDNS.info page tested for this comparison only referenced an IPv4 address and made no mention of IPv6 either way, so this page marks that point as unknown rather than asserting a feature ViewDNS may or may not have. AdminKit's reverse DNS tool supports both IPv4 and IPv6.
Is ViewDNS.info a bigger tool than AdminKit's reverse DNS check?
In breadth, yes. ViewDNS.info's own homepage lists around 25 tools (reverse IP, Whois, DNS records, port scanner and more) plus a paid API. AdminKit's reverse DNS check is one tool within AdminKit's own smaller set of free network checks — this page isn't claiming parity with ViewDNS's tool count.
Does this page use ViewDNS.info's logo or brand assets?
No. ViewDNS.info is referred to by name only (nominative use) to describe and compare a publicly available tool. AdminKit is not affiliated with or endorsed by ViewDNS.info.
