NS TTL Discrepancy
Warning: Your NS records at your authoritative DNS servers have TTLs that do not match what the parent servers report:
ns1.domain.com. [TTL 172800 at parent; 1800 at FIRSTIP]
ns2.domain.com. [TTL 172800 at parent; 1800 at FIRSTIP]
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.
ns1.domain.com. [TTL 172800 at parent; 1800 at FIRSTIP]
ns2.domain.com. [TTL 172800 at parent; 1800 at FIRSTIP]
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.
