Deep Dig is an advanced DNS lookup utility developed by Pavel Ahafonau. This iPhone app offers DNS trace support and a comprehensive history feature. With Deep Dig, you can quickly lookup DNS records by specifying record types, custom servers, ports, and other options, just like you would with the dig command line utility.

The app supports various record types, including A, AAAA, ANY, CNAME, PTR, NS, MX, SOA, and SRV records. You can easily add the record type into your query or use the "-t type" option. Deep Dig also allows you to use the "+trace" and "+all" options directly in the query or hostname field.

One of the standout features of Deep Dig is the ability to use custom DNS servers and ports. You can specify the host and port using the "-h host" and "-p port" options or simply type it in the query as The app also supports DNS queries to local multicast IP addresses automatically.

In addition, Deep Dig supports querying Bonjour/mDNS servers and LLMNR servers. It even provides automatic reverse DNS (PTR) record lookup when you enter an IPv4 or IPv6 address. Furthermore, the app offers automatic Geo IP country lookup when resolving an IP or domain name.
