Authorative DNS server that resolves more often (better)


#1

The authorative DNS server on a Peplink 310hw2 firmware 5.4.6s14 build 1465 doesn’t resolve very well.

domaina.tld has NS records that point to servers
where the hostname.domaina.tld is a CNAME for hostname.domainb.com

hostname.domainb.com has 2 NS records,
1 pointing to host1.dnsalias.net (pointing to IP of WAN1 on the Peplink)
1 pointing to host2.dnsalias.net (pointing to IP of WAN2 on the Peplink)

Resolving test ran from http://just-dnslookup.com/ results are below.

For hostname.domaina.tld results are
3x Nameserver error: Server failure
1x No A records found for hostname.domaina.tld
6x Checkpoint temporarily not available
50x correct IP address

For hostname.domainb.tld results are
1x Nameserver error: Server failure
6x Checkpoint temporarily not available
53x correct IP address

For host1.dnsalias.net results are
6x Checkpoint temporarily not available
54x correct IP address

For host2.dnsalias.net results are
6x Checkpoint temporarily not available
54x correct IP address
