DNS prepared for this application guide, SPF, DKIM ve DMARC DNS How to Create Records? It explains what data will be recorded in the process, which steps will be applied and how to prove the result.

Menu names may vary according to the version used. Therefore, write the target on the screen, the service to be affected and the expected value after the transaction begins. Authorized name server addresses and registration TTL only local without verifying value DNS do not trust cache.

## Before the process starts

- Find the opposite of the menus to be used.
- Save current security rules.
- Note who the setting and why it changes.
- Determine the threshold that will be stopped in failure.

## Step by step app

1. Which name server set of domain name uses WHOIS and authorized DNS Verify it with your query.
2. Current registration name, type, goal and TTL Take screenshot or note of the value.
3. Be careful not to combine the registration name twice as possible, to do typing and final point error in the target.
4. Ratchet for the same name A, AAAA or CNAME Check records.
5. Verify that the new response has been published directly from authorized servers.
6. Local and general DNS Take into account that old responses can be seen until the cache is renewed.

## Verification and troubleshooting

Apply a small reading-write test first, then compare the error and resource charts with the previous period. Opening a single page can not prove that all functions are healthy.

- Is the form or session process completed?
- Are there unexpected increase in resource consumption?
- Does the alert system produce new errors?

## Safety and continuity notes

Do not delete live data in bulk. Get to the quarantine before suspicious file or registration, apply permanent transaction after integrity and backup control.

Return to the final successful situation instead of adding new settings in the unforeseen situation. Check the records at the trading time and repeat the same test with one variable.
