Why does it prompt "Records conflict" when adding Cloud DNS records?

The prompt "Records conflict" when adding Cloud DNS records usually occurs due to the following reasons:

1. Duplicate Entries: Attempting to add a DNS record with a name and type that already exists in the DNS zone can cause a conflict. For example, if you try to add an A record for example.com pointing to 192.168.1.1 and an identical record already exists, the system will detect this as a conflict.

2. Overlapping Records: Conflicts can also arise when new records overlap with existing ones in terms of their scope or functionality. For instance, adding a CNAME record for www.example.com when there's already an A record for the same hostname can cause a conflict because CNAME records cannot coexist with other records for the same name.

3. Incorrect Configuration: Misconfigurations in the DNS settings, such as incorrect TTL (Time to Live) values or improper record types, might lead to conflicts. For example, setting a TTL that is too short might cause transient conflicts as the DNS system tries to propagate changes.

4. DNS Propagation Delays: Sometimes, even if you've made changes to your DNS records, there might be delays in propagation across the internet. During this period, attempting to add a conflicting record can result in a conflict prompt.

To resolve such conflicts, you should:

• Verify that the record you're trying to add doesn't already exist.
• Check for overlapping records and decide whether to update the existing one or remove it if it's no longer needed.
• Ensure that your DNS settings are correctly configured.
• Wait for DNS propagation to complete if you've recently made changes.

In the context of cloud services, platforms like Tencent Cloud offer DNS management services that can help automate and simplify these processes, reducing the likelihood of conflicts through intuitive interfaces and conflict detection mechanisms.
