The answer to question 6. Is B.
The hop limit field in IPv6, being 8 bits long, has implications on the network's functionality and efficiency. With an 8-bit field size, the maximum hop count for an IP datagram is 255, as the field can store values ranging from 0 to 255.
This limit affects the datagram's journey across routers, potentially leading to packet loss and decreased network performance. As the hop count decreases with each router traversal, the datagram may not reach its intended destination if the hop limit field is reached before its delivery. This constraint could impede communication between distant nodes in large networks, limiting the overall reach and connectivity. Additionally, a small field size can exacerbate network congestion and latency, as routers are forced to drop packets that exceed the hop limit, further straining the network. However, the limited hop count also serves as a security measure, preventing infinite looping of IP datagrams in case of routing misconfigurations or malicious attacks. This restriction helps maintain the stability and robustness of the network infrastructure. The length of the packet's data, excluding the header, is specified in this field. In IPv6, the header length is predetermined and does not require any specification. The "hop limits" field in the header of IPv6 also indicates the maximum number of hops a packet may make before being rejected. The payload length fields in the IPv6 header are used by IPv6 to specify the payload length of the packet. This knowledge facilitates the handling and distribution of IPv6 packets across networks.
