Question
Does Plesk support glue records?
Answer
Yes. Glue records can be added in Plesk at Domains > example.com > DNS Settings.
It is obligatory to create glue records in case NS record is located in domain's zone. For example, if the domain example.com is created and NS record is ns1.example.com, A record for the ns1.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 203.0.113.2
