RBL Status - so far the only Multi-DNSBL checker app for iOS - lets you quickly check a list of your hosts against multiple DNS blacklists.

Having checked your hosts against multiple DNS blackhole lists, RBL Status presents the information in a simple and convenient way. You can quickly and easily determine which RBLs are currently listing hosts from your monitoring list.

The system employs asynchronous algorithms for DNSBL lookups, which allows RBL Status to operate really fast. Only fractions of a second are taken to check a large number of lists.

- Group hosts into multiple checklists
- E-mail check results
- Predefined DNSBLs for your convenience
- Possibility to add custom DNSBLs
- WHOIS hostnames, IP addresses and PTRs
- Ultrafast asynchronous network I/O


· Spyglass - augmented reality & GPS navigator
· Scany - Wi-Fi/LAN network scanner

cool idea / app , works well!

I love the app and the concept of being able to quickly check the various blacklist services, definitely worth the two dollars.

however one feature I would really like to see added is the ability to quickly pre-fill/input your current public IP.

as a multi site Internet provider/ISP, it would be handy to quickly check when on-site at my many locations without having to look up my current public IP address to input it. (I am aware of the page that in the app that shows your current IP, so maybe there could be a button to copy or pre-fill that IP into the first page.)

( I often use blacklists as a check against any malicious or compromised hosts/customers that might be on my one of my networks and thus emanating from one of my IPs / locations) thanks

Brilliant isn't the word for it!

I've already used this to find out where my domain is listed in the RBL since some of my customers couldn't get my emails. With this app, it was extremely fast, and I was easily able to find the RBL that had my domain in it, and that made it so much easier to file to be removed (since we aren't a spam source).

Great work!

It does exactly what it says, though a paranoid admin should sign up for a free service like mxtoolbox. That way you don't have to manually check and can get realtime notifications of this as well as smtp downtime.
