I found two issues with zone exporter:
1. We duplicate the glue records. For instance
A.ROOT-SERVERS.NET. AAAA 2001:503:BA3E:0:0:0:2:30 and
A.ROOT-SERVERS.NET. A 198.41.0.4
are showing up under the SOA statement and also in the list of glue records.
2. Instead of doing an explicit TTL statement we should out put TTL statement for each RR like zone file you get when you run dig command ( dig @f.root-servers.net . axfr > root.zone)
I’m attaching RZM generative root zone file and the zone file I got from the dig command
1. Fixed.
2. Changed.
Please let me know whether or not the format is fine for you.
