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.
Which IPv4 header field is responsible for defining the priority of the packet?
differentiated services
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.
Contrast the IPv4 and the IPv6 header fields?
Simplified header format. IPv6 has a fixed length header, which does not include most of the options an IPv4 header can include. Even though the IPv6 header contains two 128 bit addresses (source and destination IP address) the whole header has a fixed length of 40 bytes only. This allows for faster processing. Options are dealt with in extension headers, which are only inserted after the IPv6 header if needed. So for instance if a packet needs to be fragmented, the fragmentation header is inserted after the IPv6 header. The basic set of extension headers is defined in RFC 2460.
The source IP address for an IPv4 datagram is stored where in the header?
4th longword (bytes 13-16)
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 can dns distinguish between ipv4 and ipv6 host in determining which resource record to return?
It reads the protocol/bit stream/header
How many fields are there in IPv4 header?
UDP is a Transport layer protocol or fourth layer protocol. UDP is a connection less protocol used in transport layer. UDP header have four fields in total .
Which fields of the IPv4 header change from router to router and why they change?
IP address remains the same. Mac address changes from router to router.
When a tunnel mode is used a new outer ip header is constructed for both ipv4 and ipv6 indicate the relationship of each outer ip header field and each extension header in the outer packet to the corr?
i naw the answer but you dont answer my guestinq first my giestion i want to ask what is mean by outer plantes
What is the maximum permittable size in bits for an IPv4 packet?
The maximum permissible size for an IPv4 packet is 65,535 bytes, which includes both the header and the data payload. Since the maximum size of the header is 60 bytes, this allows for a maximum data payload of 65,475 bytes. However, in practical use, the Maximum Transmission Unit (MTU) often limits the size of packets on networks, typically to 1,500 bytes for Ethernet.
