Five concrete examples of the DNS Lookup in real use. Each one shows the situation, what you put in and what comes out, so you can copy the structure, swap in your details and adapt it this week.
Example 1: Confirming a domain points at the right server
The task: Confirming a domain points at the right server. You start from a domain name such as example.com and the record types you want to see.. The tool returns the A, AAAA, CNAME, MX and TXT records returned for the domain, each with its value and time to live where reported., giving you the current published records for that name instead of what you remember configuring. you can edit rather than a blank page.
Make it yours: add one detail the tool cannot know - a real number, a name, a constraint - then read the result once end to end before you keep it.
Example 2: Checking mail routing after a migration
The task: Checking mail routing after a migration. You start from a domain name such as example.com and the record types you want to see.. The tool returns the A, AAAA, CNAME, MX and TXT records returned for the domain, each with its value and time to live where reported., giving you the current published records for that name instead of what you remember configuring. you can edit rather than a blank page.
Make it yours: add one detail the tool cannot know - a real number, a name, a constraint - then read the result once end to end before you keep it.
Example 3: Verifying a domain for a third party service
The task: Verifying a domain for a third party service. You start from a domain name such as example.com and the record types you want to see.. The tool returns the A, AAAA, CNAME, MX and TXT records returned for the domain, each with its value and time to live where reported., giving you the current published records for that name instead of what you remember configuring. you can edit rather than a blank page.
Make it yours: add one detail the tool cannot know - a real number, a name, a constraint - then read the result once end to end before you keep it.
Example 4: Reviewing TXT records for policy entries
The task: Reviewing TXT records for policy entries. You start from a domain name such as example.com and the record types you want to see.. The tool returns the A, AAAA, CNAME, MX and TXT records returned for the domain, each with its value and time to live where reported., giving you the current published records for that name instead of what you remember configuring. you can edit rather than a blank page.
Make it yours: add one detail the tool cannot know - a real number, a name, a constraint - then read the result once end to end before you keep it.
Example 5: Comparing records before and after a change
The task: Comparing records before and after a change. You start from a domain name such as example.com and the record types you want to see.. The tool returns the A, AAAA, CNAME, MX and TXT records returned for the domain, each with its value and time to live where reported., giving you the current published records for that name instead of what you remember configuring. you can edit rather than a blank page.
Make it yours: add one detail the tool cannot know - a real number, a name, a constraint - then read the result once end to end before you keep it.
A Full Worked Example
Input: example.com queried for MX and TXT
Mail exchange records with their priorities and the TXT records published for the domain, each with its value.
The pattern behind every example above: context and constraints go in, structure comes out, and your edit makes it true.
How to Build Your Own Examples
- Take a task already on your calendar for this week.
- Write the brief in two sentences: the job and the audience.
- Generate, compare against the version you would have written manually.
- Save the prompt alongside the result so the second run takes seconds.
Getting More From Each Example
Most people stop at the first result. Generate a second version with one changed variable - length, tone or angle - and compare. The better version usually appears on the second run, not the first.
Frequently Asked Questions
How long do changes take to appear?
Records carry a time to live, so resolvers keep the old value until it expires and propagation finishes shortly after.
Why do I see different results than my provider shows?
You may be querying a cached copy or a different name server, so requery after the record time to live passes.
Which record types can I query?
Address, alias, mail and text records are covered here, including A, AAAA, CNAME, MX and TXT lookups.
Are my queries stored?
No - queries run for your check with nothing retained.
