I did some API updates to a zone. For the serial I used 2017020601 but the zone did not update and afterwords I found that the zone serial in is set to: 4294967295 which is really strange. I have around 100 zones and over half are set to that same exact 4294967295. In dns_soa the zone serial is the same 4294967295 but in dns_rr the serial is in the 2017020601 type format. There are some from 2016 and some from 2017 but none with the 4294967295 format. The zone that I modified with the API did not update on either DNS server. Not really sure how to troubleshoot this. Can I manually reset the serial for the zone in dns_soa and dns_rr? Is there some sort of DEBUG entry I can set to see what is happening? Any advice to get this zone updating is greatly appreciated.
