Does Plesk support glue records?
Glue records can be added in Plesk > Domains > example.com > DNS Settings for any required domain.
It is obligatory to create glue records in case
NS record is located in domain's zone. For example, if domain example.com is created and
NS record is ns.example.com,
A record for the ns.example.com must be defined. The following pair of records are known as glue:
example.com IN NS ns1.example.com
ns1.example.com IN A 126.96.36.199
