DNS Explorer 4.06 for macOS Is Out

Picture the least glamorous kind of release note there is. No new feature. No redesign. Just a line that reads: fixed a bug in subdomain lookup retry handling. You would be forgiven for scrolling right past it.

Don't. Retry logic is the part nobody thinks about until it is the only part that matters. When you lean on a tool for large-scale subdomain work, you want every lookup that stumbles to try again on its own. That is what got fixed here. The release notes don't spell out what the bug did in the field, and we won't invent a story for it. But if subdomain lookups are your daily work, a fix to their retry handling is worth the update.

That is the whole story of DNS Explorer 4.06 for macOS, released in July 2026. It is a maintenance release, and it is proud of it.

What changed

Two things, both small, both linked to their source in the release notes:

• Subdomain retry, fixed. The release notes put it plainly: the update “fixed a bug in subdomain lookup retry handling”. If you lean on DNS Explorer for large-scale subdomain work, this is the reason to update. The notes don't elaborate further, and that's fine — a fix is a fix.
• The in-app Assistant link, updated. The same notes report an updated in-app link to the DNSai Assistant. That's the extent of it: the shortcut inside the app now points to its current destination.

That's it. No new feature, no reinvented interface. The app that was already a powerful domain DNS record lookup tool tailored for efficiency and large-scale operations is now the same tool with one fewer sharp edge.

Why “signed and notarized” is the quiet headline

Here is the part that sounds like fine print and isn't. The macOS build is a native application, signed and notarized via Apple Direct Distribution. Translated out of Apple-speak: when you open it, your Mac already trusts it.

Apple's own documentation explains the machinery. As Apple describes Gatekeeper, “all software in macOS is checked for known malicious content the first time it's opened, regardless of how it arrived on the Mac”. Notarization is how an app clears that check ahead of time. Apple verifies it is “notarized by Apple to be free of known malicious content, and hasn't been altered” since. So instead of the ominous Gatekeeper warning that greets so much downloaded software, DNS Explorer just opens.

A note for Windows users

Nothing to do. This release is macOS only. The download page lists macOS at 4.06 and Windows 11 at 4.4.0.0, and that Windows build is unchanged by this cycle. The version numbers differ by platform, so don't read 4.4.0.0 as “behind.” The two builds simply version independently, and this round of notes covers only the Mac.

So: a bug in subdomain retry handling is gone, the in-app Assistant link is updated, and the app opens without a fight. Not the release you'll frame on a wall. Just the one your next subdomain sweep will quietly thank you for. Grab 4.06 here.
