1)

Would it be possible to have a DNS A record point to a non-existent / supposed to be non-existent IP?

Essentially is there anything that prevents a DNS record from linking to anything?

Ex. Could someone go into a DNS record and change it to point to malicious things. ex. would it be possible for someone to point http://www.company.com –> 1.1.1.1 which is the IP for a malicious attacker?

2)

From this:

Ex. http://www.team-cymru.org/Services/Bogons/http.html

Those bogons. Would it be possible to have a DNS record point to one of them and some how ‘fake’ that they are this IP ?
I’m thinking yes via IP Spoofing?
Would there be someway for a website to emulate that it is actually a different IP address via a combination of DNS and IP trickery?

  • What prevents someone from saying that a certain DNS links to any IP. is there any sort of checking?
  • Could a DNS be used to hide the actual service provider and somehow provide service from IP (A) but ‘say’ it’s providing service from IP (B). As DNS, I believe, is only supposed to tell you the IP to connect to I don’t think this is possible yet I’m not sure.

Thanks,

Requesting for reopen: Why is this not a valid question? This from my standpoint is a valid cybersecurity question that I face.

    IP addresses always exist. They are just numbers. What might happen is that a name is resolved to an address because there is a dns record doing so, whilst there is no server listeing at the address. Or even no system using that address.

    If it’s possible to ‘use’ such circumstances to whatever depends on a million things, so there is no way to give an answer without a clear question.
