I keep getting the results that my connection has changed from a0k to the following (it’s been this way since I listed back with Cloudflare which is the reason I’m asking here):
“Your nameserver does not include A records when asked for your NS records.”
(*Is this a problem?)
“Your nameservers are on the same Class C IP range. This is very bad if you want to be found in the case of outage, or even worst, problems!”
I’m not sure about the following one but list it here anyway.
Your DNS servers return the following MX records: elma.ns.Cloudflare.com. :
Your domain works, so I wouldn’t worry about their complaints. That first warning is weird. It’s as if they want a name server to have an “A” record for itself. Maybe they’re thinking of GLUE records. Regardless, the name servers are fine.
As for last warning on MX records, you only need an MX record if you receive email at that domain. As they discovered, your domain doesn’t have an MX record. I suspect this is intentional, as you’d notice a lack of email right away. NP probably stands for Not Present.
See, I kind of gathered that everything was working fine so I was just on another fishing expedition.
Not to worry sdayman, I run out of topics quickly so the questions will peter out soon enough "
Yes…a firewall. I run VPSs, so I have complete control over my server’s firewall. I block any access that doesn’t come through Cloudflare…but I do whitelist my home’s IP address for my own access.
That’s a better question for StackOverflow, as it’s a server configuration question. I’m there are lots of tutorials for iptables and Cloudflare out there.
