[ Classification Level: PUBLIC ] Sorry, I misread the thread. I thought it was for all values in the SOA. RFC 1982 is specific to only the serial, not relevant to REFRESH/RETRY/EXPIRE. Not enough caffeine... - Kevin On Fri, Oct 18,

[ Classification Level: PUBLIC ] Apologies if this sounds condescending, but I haven't seen RFC 1982 mentioned in this thread so far. While that RFC may not be the last word on the acceptable values of SOA.SERIAL, in normal operation, it does contain some advice on how to effectuate (or avoid) a

[DNSOP] valid value range for SOA REFRESH/RETRY/EXPIRE

2019-10-17 Thread 神明達哉
I have a question for which I believe there's an answer already that I couldn't find: what's the valid range for SOA REFRESH/RETRY/EXPIRE values? RFC1035 says: REFRESH A 32 bit time interval ... RETRY A 32 bit time interval ... EXPIRE A 32 bit time value ... and
