Click Add Private Field enter the private field name in the pop-up box, and click OK

Note:

• If the private field name conflicts with the real domain name of the public network, after setting resolution record and associating VPC, the resolution of the domain name in VPC environment is subject to the resolution record of intranet DNS, and public network resolution is still used outside VPC environment.
• The private field does not support the adding of top level domain name.
• The private field does not support Chinese temporarily with supported domain name length of 240.
• It does not support private field suffixed by baidubce.com, which might conflict with the internal service domain name.

After the completion of adding, you can see the added private field in the private field list.
