@elormkdaniel depends, what's the subnet mask that was assigned? Most likely is C, but if we take the question literally, seeing as a host "get's an IP address", it didn't set it itself because it apparently could reach a DNS server, I'd say E) The DHCP admin has a twisted sense of humour.
The likely answer is Layer 7 (D) in 99.999% of all cases, but an edge scenario where it would be Layer 4 (C) would be:
- The host machine is using external DNS resolvers such as hard coded for 1.1.1.1, 8.8.8.8 or 9.9.9.9 etc… and not using SecureDNS (DNS over HTTPS)
- An administrator on the network added a firewall rule to block TCP/UDP outbound to port 53 (possibly to enforce or monitor DNS lookups, ie. pihole or Umbrella)
- The firewall is allowing ICMP, ping still works.
- The firewall is allowing TCP over port 443, https connections would still be permitted.
It’s a rare one but I’ve run into similar issues when I bring my laptop onto a locked down environment where they want to force me to use their DNS and I forgot I left 9.9.9.9 hard coded on my NIC and nothing resolves. 😅
