### 5/5 — This needs to be updated

*2024-09-21, version 9.14.2*

This tool needs to be updated to the latest Bind (9.20.2)

### 4/5 — does what it says

*2023-10-28*

Only issues are non-functional; say switching the Defaul DNS servers, you have to go via Options->Servers, rather than a direct link on the rather sparse interface.

Also appears abandoned, and has no privacy statement, else would be a five star review.

### 5/5 — Funktioniert immer noch

*2023-09-04, version 9.14.2*

Prima App - auch wenn das letzte Update 3 Jahre her ist

### 2/5 — Weird

*2023-01-19, version 9.14.2*

It feels like a fake BIND ISC DIG, and to make it look real use copy the original terminal format from desktop applications, besides it won’t automatically timeout, no cancel button, can’t even add unconventional ports… For normal DNS checking, it’s okay, more? It can’t.

### 3/5 — Please update. BIND 9.14 is EOL.

*2022-08-28, version 9.14.2*

I find this app to be indispensable, however, it’s in need of an update. Currently based off BIND 9.14, a version that has been EOL since 2020. The current stable builds as of this review (2022-08-27) are 9.16 and 9.18. This would be a 5-star app for me if it were updated.

### 2/5 — Can not change port

*2021-02-13, version 9.14.2*

Can not use “-p” option to change port as the real dig command.

### 2/5 — Pretty good except +timeout doesn’t seem to work

*2018-04-24, version 912.0.1*

The app seems to work pretty well so long as your DNS servers are working; if your server has on issue, the app won’t timeout, even if you explicitly set the option, it just spins until you force quit the app.

### 5/5 — Tut was sie soll

*2018-01-14, version 911.0.1*

Schön wäre es noch die verschiedenen Anfragetypen (MX, CNAME etc.) irgendwo auszuweisen, im Moment muss ich raten

### 5/5 — Awesome

*2017-07-04, version 911.0.1*

Works like a charm!
