[b] Among the list of fields within an IP header is the fragment offset industry, indicating the commencing place, or offset, of the information contained in a very fragmented packet relative to the information in the first packet. If your sum on the offset and measurement of one fragmented packet differs from that of another fragmented packet, the packets overlap. When this comes about, a server susceptible to teardrop attacks is not able to reassemble the packets resulting in a denial-of-assistance issue.[106]
