SYN floods (a source starvation attack) may also be employed. Newer equipment can use DNS servers for DoS applications. Not like MyDoom's DDoS system, botnets might be turned from any IP handle. Script kiddies utilize them to deny The provision of well-known Internet sites to authentic buyers.
As a diversion: DDoS attacks may also be utilised like a distraction to help keep an organization’s constrained incident reaction resources engaged although perpetrating a different, much more stealthier attack in A different Portion of the infrastructure concurrently.

[b] One of several fields within an IP header could be the fragment offset area, indicating the starting situation, or offset, of the data contained within a fragmented packet relative to the information in the initial packet. If your sum with the offset and size of 1 fragmented packet differs from that of another fragmented packet, the packets overlap. When this occurs, a server liable to teardrop attacks is not able to reassemble the packets causing a denial-of-service issue.[106]
