Each host on an IP network must have an IP address. An IPv4 address is 32 bits long and consists of two parts: network ID and host ID. A network ID uniquely identifies a network segment or a group of network segments. A network ID can be obtained by converting an IP address and subn...

An IPv4 header typically spans 20 bytes and consists of several fields. Here’s a brief overview of its components: Version: 4 bits indicating the IP version (IPv4). Header Length (IHL): 4 bits that define the header’s length. Type of Service (ToS): 8 bits indicating the quality of ...
Remember that a 32-bit IP address consists of a network address and a host address. The subnet mask determines the number of bits used for the network address and the number of bits used for the host address. The IP address classes have a natural or standard subnet mask, as shown in ...
With VLAN maps, forwarding of packets is permitted or denied, based on the action specified in the map. Figure 2. Using VLAN Maps to Control Traffic. This figure shows how a VLAN map is applied to prevent a specific type of traffic from Ho...
The IPv6 header is of 40 bytes and consists of the following fields: Version:It is of 4 bits and contains the version of IP which is 6. Traffic class:It is of 8 bits and denotes the type of service used for routing packets.
The standard operation of a RIP for IP router consists of three processes: initialization, when the router learns the routes of the internetwork from neighboring routers; ongoing periodic advertisements; and advertisement of unreachable routes when a router is brought down intentionally or fails. Ini...
IGMP version 1 consists of the following two types of messages: Host Membership Report Host Membership Query The following table describes the fields in IGMP version 1 messages. Fields in IGMP Version 1 Messages Expand table IGMP Version 1 FieldLengthDescription Version 4 bits Identifies the IG...
This method consists of filling bits into the padding of transmission symbols. Another solution has been proposed, which is using DFT-precoded OFDM. The authors suggested sending a cover signal in addition to the weak secret signal rather than delivering the weak signal to the authorized recipient...
The actual ICMP payload consists of query/informational messages and error messages. First, we’ll look at the Echo Request/Reply messages, commonly referred to as “pinging” in networking: structicmp_v4_echo{uint16_tid;uint16_tseq;uint8_tdata[];}__attribute__((packed)); ...
