    Hi !!

    I have somo problems....

    When I check my domains in DNSReport.com appears this warns:


    WARN NS TTL discrepancy

    Warning: Your NS records at your authoritative DNS servers have TTLs that do not match what the parent servers report:

    ns2.myserver.ws. [TTL 10340 at parent; 14400 at 69.10.149.142]
    ns1.myserver.ws. [TTL 10340 at parent; 14400 at 69.10.149.142]

    In some cases, this can cause some serious problems. For example, if the parent servers have a 172800 second TTL (48 hours), and your authoritative DNS servers report a TTL of 3600 seconds (1 hour), you are saying that the parent DNS servers do not have the correct information. But, after 1 hour your DNS records may time out. At that point a DNS resolver will need to get fresh NS records. This can cause a serious problem in some cases.


    All my domains hosted in my server has this problems, and in each one appear with different TTLs ( TTL 10340 at parent or TTL 11078 at parent )

    How can I fix this??

    Thanks
