Two ICMPv6 messages not present in ICMP for IPv4 are Neighbor Solicitation and Neighbor Advertisement. These messages are used in the Neighbor Discovery Protocol (NDP) to facilitate address resolution and to determine the link-layer addresses of neighboring nodes. Additionally, ICMPv6 includes the Router Solicitation and Router Advertisement messages, which help in the discovery of routers on the local network, a feature not directly available in IPv4 ICMP.
What else can I help you with?
What transport layer protocol does ping use?
Assuming IPv4 ICMP. Ping uses IP for transport. Ping in itself is an "Echo Request", which is a function of the ICMP protocol. The IP Packet will carry the ICMP protocol from end-to-end. ICMP has a protocol number of 1, so the "Protocol" field in the IPv4 header will contain "1" as a reference to the ICMP payload. For IPv6, ICMPv6 is used, and the transport will be IPv6.
Which two ICMP messages are used by both IPv4 and IPv6 protocols?
route redirection and protocol unreachable
Neighbor discovery is an IPv6 feature that combines which IPv4 mechanisms?
ARP ICMP IRDP
What is the minimum maximum size of ICMP packet?
The minimum size of an ICMP packet is 8 bytes, which includes the 8-byte ICMP header without any additional data. The maximum size of an ICMP packet is 65,535 bytes, which includes the maximum payload that can be carried within an IPv4 packet.
What Command is used to test the IPv4 protocol stack?
The command used to test the IPv4 protocol stack is ping. This command sends Internet Control Message Protocol (ICMP) echo request packets to a specified IP address and waits for a response, helping to diagnose network connectivity issues. By using ping, users can determine if a host is reachable over the network and measure the round-trip time for messages sent.
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 is IPv4 Mechanisms?

What is the length in bits of a logical IP address IPv4 and IPv6?
32 bits (for IPv4), or 128 bits (for IPv6).32 bits (for IPv4), or 128 bits (for IPv6).32 bits (for IPv4), or 128 bits (for IPv6).32 bits (for IPv4), or 128 bits (for IPv6).
When was ipv4 created?
IPv4 was described in RFC 791 in September 1981.
What is the difference between ipv4 and ip address?
IPV4 is a kind of IP Address.
Minimum bytes in IPv4 header?
Minimal bytes required in IPv4 header are 20 i.e. 20 bytes are mandatory. And total bytes in IPv4 header are 60.
