I have made a verification of a site of mine via intodns.com.
I have received the following warnings:
Different subnets - WARNING: Not all of your nameservers are in different subnets Different autonomous systems- WARNING: Single point of failure SOA MNAME entry - WARNING: SOA MNAME (mydomain.com) is not listed as a primary nameserver at your parent nameserver!
Does anyone know how to fix these? I see that many domains are having these issues. Apparently, they are working fine (including my site). I just want to know if I should be worried about this.
Thanks in advance, Gabriel
