Can you hide DNS records?
No. The only way to reliably hide data from a client is to ensure that it can never get the data to begin with. Assume that existence of your DNS records will be spread among whoever has access to them, either by word of mouth or by observing the packets.
Will VPN hide DNS?
This is a little trickier, some VPN providers are able to tunnel your DNS requests through your encrypted VPN, whereas others do not offer this ability. Unfortunately, DNS is an unencrypted protocol, so your ISP can monitor your DNS traffic, even if you change your DNS provider to not use your ISP’s service.
What is dnsmasq vulnerability?
Recently, security researchers discovered new issues that continue to make dnsmasq vulnerable. These vulnerabilities can lead to DNS cache poisoning, denial of service (DoS) and possibly remote code execution (RCE). In this blog, I will review these vulnerabilities in dnsmasq, with a deep dive on DNS cache poisoning.
Does Cloudflare hide DNS records?
Overview. When your DNS records are orange-clouded, Cloudflare speeds up and protects your site. A dig query against your orange-clouded root domain returns a Cloudflare IP address. This way, your origin server’s IP address remains concealed from the public.
How to enforce Dnsmasq to use an upstream DNS.?
Also permitted is a -S flag which gives a domain but no IP address; this tells dnsmasq that a domain is local and it may answer queries from /etc/hosts or DHCP but should never forward queries on that domain to any upstream servers. local is a synonym for server to make configuration files clearer in this case.
How to setup Dnsmasq as an authoritative DNS server?
I’d like to setup dnsmasq as an authoritative DNS server, but can’t find any good guides for it. So could somebody please post a sample configuration of dnsmasq as an authoritative DNS server (with some basic options, such as A records)?
Why is the query port flag ignored in Dnsmasq?
It should be an address belonging to the machine on which dnsmasq is running otherwise this server line will be logged and then ignored. The query-port flag is ignored for any servers which have a source address specified but the port may be specified directly as part of the source address.
I intend to setup an authoritative DNS server so I can have automatic renewal of Let’s Encrypt certificates using the DNS-01 challenge.
