How do DNS providers differ in TXT handling?

Provider differences that affect TXT records:

Quote handling: Some auto-add quotes, some require them, some handle both inconsistently.

String splitting: Some split long records automatically, some truncate, some require manual splitting.

Character limits: UI limits may differ from DNS protocol limits.

Escape characters: Handling of special characters varies.

Propagation time: Some update instantly, some delay.

Multiple records: Some make it hard to have multiple TXT records at the same name.

Recommendation: After any change, verify with external tools (dig, MXToolbox) that the actual published record matches your intent.

Each registry office has slightly different forms and procedures. Verify your final registration regardless of provider.
