It aims to overwhelm its target with malicious fragmented data packets, which the victim is not able to reconstruct and finally is incapable of operating. This attack takes advantage of a specific vulnerability inside the TCP/IP reassembly operation. The fragmented data packets exceed the capacity of the victim until, at some point, it crashes in its try to process them.

To properly understand DNS and its function, we must investigate each of the DNS records, how they work, and why they exist. There are many, but there are a few that we must understand from the start. This is why we will begin by explaining the DNS SOA record.
What is DNS SOA record?
The DNS SOA record is the start of authority. It is the beginning of the chain of authority that the DNS has. It will point which server, from all the nameservers that you have, contains the original zone file. This server will be the authoritative DNS server, and it will have all the important information about the zone.
Inside the DNS SOA record, there you can find information about the zone transfer, the rate of refreshing, and the rate for retry if not refreshed properly. Also, inside it, you will see the DNS administrator’s contact information.
Here you can find the structure of the DNS SOA record!
