Duplicated service location records RRS feed

  • Question

  • Hi,

    I can see that there are duplicates of records within DNS, the duplicates are the same name but with capital letters, some are but not all of them. Is there a reason for duplicae records with capital letters, is it ok to have 2 records or should I delete one of them ?

    Name    Type    Data    Timestamp
    _kerberos    Service Location (SRV)    [0][100][88] server1.domain.local.    ?18.?10.?2018 17:00:00
    _kerberos    Service Location (SRV)    [0][100][88] server3.domain.local.    ?16.?10.?2018 20:00:00
    _kerberos    Service Location (SRV)    [0][100][88] SERVER2.domain.local.    ?13.?09.?2018 15:00:00
    _kerberos    Service Location (SRV)    [0][100][88] SERVER1.domain.local.    ?19.?09.?2018 10:00:00
    _kerberos    Service Location (SRV)    [0][100][88] server2.domain.local.    ?09.?08.?2018 12:00:00
    _ldap    Service Location (SRV)    [0][100][389] server2.domain.local.    ?09.?08.?2018 12:00:00
    _ldap    Service Location (SRV)    [0][100][389] SERVER2.domain.local.    ?09.?08.?2018 14:00:00
    _ldap    Service Location (SRV)    [0][100][389] server3.domain.local.    ?16.?10.?2018 20:00:00
    _ldap    Service Location (SRV)    [0][100][389] server1.domain.local.    ?18.?10.?2018 17:00:00

  • Hi,

       

    Thanks for your question.

    According to your description, there are duplicates of records within DNS. However, the same record has different timestamps. I suggest you enable the scavenging option of DNS and set a appropriate time for scavenging. Just check whether the duplicate record still exist. 

    You can refer to:

  • Hi,

    Thanks for reply, will look into that.

    Btw what time perspective do you recommend when it comes to configuring it ? Use default ? Guess it depends, but what do you have ?

  • Hi,

    Thanks for your reply.

    The time should be decided by your usage habits.

    You can use the default setting first and check whether the duplicate record still exist.

    Please feel free to let me know if you need any assistance.
