What is the difference between IPv4 and IP?
IP is the internet protocol that uniquely identifies a system on a network and there is no difference between IP and IPv4 infact IPv4 is a version of like IPv6.
How do you stop the century-link search page from popping up?
Navigate to your Ethernet card settings, IPV4 and choose manual for your DNS server and use Googles free DNS servers: Primary: 8.8.8.8 Secondary: 8.8.4.4
What is the difference between IPv4 and?
IPv4 1) Header (20-60 bytes). 2) Routed Protocol. 3) Types of address: i) Unicast ii) Multicast iii) Broadcast (limited/Direct) 4) 32-bit address. 5) Address space is 2^32. 6) Format of address : Decimal dotted. 7) IPsecurity support is optional. IPv6 1) Header is fixed (20 bytes). 2) ICMP6, IP 3) Types of address: i) Unicast ii) Multicast iii) Anycast 4) 128-bit address. 5) Address space is 2^128. 6) Format of address : colon hex notation. 7) IPsecurity support is built in.
What is the purpose of a broadcast address?
A broadcast address is used in computer networking to send data packets to all devices on a specific network segment simultaneously. It allows a single message to be distributed to multiple recipients without needing to send individual packets to each device. This is particularly useful for tasks like network discovery and certain types of communication where all devices need to receive the same information at once. In IPv4, the broadcast address is typically the highest address in a subnet.
How can we determine if an ipv4 packet is carrying an icmpv4 packet?
To determine if an IPv4 packet is carrying an ICMPv4 packet, you can examine the packet's protocol field in the IPv4 header. The protocol field specifies the type of payload the IPv4 packet carries, and for ICMPv4, this field is set to 1. Additionally, you can analyze the packet's structure; ICMPv4 packets have a specific format beginning with a type field that indicates the kind of ICMP message being transmitted.
What statement is true about the TTL value of an IPv4 packet?
it specifies the remaining " life" of the packet
What are three characteristics of ipv4?
IPv4 basic characteristics: Connectionless - No connection is established before sending data packets. Best Effort (unreliable) - No overhead is used to guarantee packet delivery. Media Independent - Operates independently of the medium carrying the data.

TTL value of an IPv4 packet?
The default gateway on host A is incorrectly configured.
Which IPv4 header field is responsible for defining the priority of the packet?
differentiated services
Could a packet with all 0s or all 1s be a legal IPv4 packet?
Yes, a packet with all 0s or all 1s can technically be a legal IPv4 packet, as long as it adheres to the IPv4 header format and other protocol specifications. However, an all-0s packet may be considered invalid in practical scenarios since it would likely represent an undefined or non-routable address. An all-1s packet, often representing a broadcast address, could be valid in certain contexts, such as for broadcasting messages to all devices on a local network.
What is The header of an IPv4 packet does not include fields required for?
The header of an IP packet does not include fields required for reliable data delivery. There are no acknowledgments of packet delivery. There is no error control for data.
How much overhead would this be if IPv6 is tunnelled over IPv4?
When tunneling IPv6 over IPv4, the overhead primarily consists of the additional IPv4 header and any encapsulation overhead. An IPv4 header is typically 20 bytes, while an IPv6 header is 40 bytes. Thus, the total overhead for tunneling one IPv6 packet over IPv4 would be 20 bytes, resulting in a total packet size increase of 20 bytes for every IPv6 packet transmitted. This additional overhead may impact performance, especially in networks with high traffic or limited bandwidth.
What contact does IPv4 make with the destination before sending a packet?
Before sending a packet, IPv4 establishes contact with the destination by using the Address Resolution Protocol (ARP) to map the destination IP address to a MAC (Media Access Control) address on the local network. If the destination is on a different network, IPv4 sends the packet to the default gateway, which is determined by the subnet mask. The packet includes the destination IP address, and the network layer handles routing it through the appropriate paths until it reaches the destination.
