Feature
Docs and Knowledge Base replace Learning
Documentation now lives under /docs: step-by-step Help center guides and a searchable Knowledge Base for DNS record references, email authentication, and WHOIS. The old Learning section is retired.
Changelog
What we've shipped for DNS research and tooling
Every improvement to the free DNS tools, bulk operations, provider health data, identifier detection, and the platform behind them. Filter by type when you only want to see new tools or fixes.
2.1.0
Feature
Bulk WHOIS lookup tool (beta)
Run up to 256 mixed domains, IPv4/IPv6 addresses, and ASNs in one batch. Results are grouped by type with per-tab CSV export and normalized RDAP/WHOIS fields.
Feature
IPv4 subnet calculator
Compute network and broadcast addresses, subnet and wildcard masks, usable host range, host counts, legacy IP class, and dotted-binary network/mask views from any IPv4 CIDR. Plain addresses default to /32; optional shareable ?cidr= query param.
2.0.0
Improvement
DNS Looks-up are better handled, and more reliable.
We have moved away from DoH (DNS over HTTPS) to using our own backend. Which allows us to easily parse, and handle the results better.
Feature
DNS Health
With all the different activity we see, I wanted to also monitor the DNS Health of the various providers. This will be important as I scale and start to build out my own DNS Hosts in the future.
Feature
Domain Digger is here.
This is similar to a tool we previously offered, but a lot better. We now identify over 100 different TXT Validation Records, 30 different MX and 50 different NS (DNS Providers). We are constantly enhancing our data, and trying to provide the best results around.
