Hello.
I checked my domain with Google: https://intodns.com/ and the check showed two warnings.
1. SOA EXPIRE. Your SOA EXPIRE number is: 3600000. That's NOT OK.
2. SOA MINIMUM TTL. Your SOA MINIMUM TTL value is: 172800. This value seems a bit high. You should consider decreasing this value to about 1-3 hours, as recommended by RFC2308. This value was used as a default TTL for records without a given TTL value and is now used for negative caching (indicates how long a resolver may cache the negative answer). RFC2308 recommends a value of 1-3 hours.
I can't fix these warnings. This is an automatically created record. What can I do? Just accept it? Or will you fix them according to RFC2308 recommendations?
