DNS Lookup on iOS: Check DNS Records Without a Terminal

If you manage domains, run servers, or handle email deliverability, you've probably used nslookup or dig in a terminal. Now you can do the same thing from your iPhone with NetKit Pro's DNS Lookup tool.

Why DNS lookup on mobile?

Because DNS issues don't wait for you to be at your desk:

• You just updated DNS records and want to check propagation
• Email isn't being delivered and you need to verify MX records
• You're debugging SPF/DKIM and need to check TXT records
• You want to see if a CDN is resolving correctly from your location

How to use it

Open NetKit Pro, tap DNS, and enter a domain name. You can also use the Quick Targets (Google, Apple, GitHub) to explore.

Filter by record type

Tap the record type buttons to filter results:

• A — IPv4 addresses
• AAAA — IPv6 addresses
• MX — Mail servers and priority
• CNAME — Canonical names (aliases)
• NS — Authoritative nameservers
• TXT — Text records (SPF, DKIM, domain verification)
• All — Show everything

Choose your DNS server

By default, queries use your system's DNS resolver. But you can switch to a different DNS server — useful for checking if records have propagated to public resolvers while your local cache still shows old values.

Real-world examples

Checking email deliverability

Query your domain with the MX filter to verify mail servers are configured correctly. Then check TXT records for SPF and DKIM entries. Missing or incorrect records are the most common cause of email landing in spam.

Verifying DNS changes

Just updated your nameservers or added a new A record? Query the domain to see if the change has propagated. Check both the default resolver and a public one to compare.

Debugging CDN setup

If your site uses a CDN like Cloudflare, query the CNAME and A records to verify traffic is being routed through the CDN. The TTL values tell you how long the records are cached.

Query timing

Every lookup shows the query completion time in milliseconds. This helps you understand DNS performance — slow queries can add noticeable delay to every connection your apps make.
