What is the maximum and minimum size of a UDP datagram?
maximum size is 512 bytes without header
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.
How many bytes is the data frame made by FCS and the header together?
14 bytes for the header and 4 bytes for the FCS (Frame Check Sequence) for a total of 18 bytes.
IP ADDRESS occupies how many bytes?
IPv4 addresses are 4 bytes. IPv6 IP addresses are 16 bytes.
What is the size of today's standard (IPv4) IP address?
The size of an IPv4 address is 32 bits, or 4 bytes.
What is The header of an IPv4?
Header is always a multiple of 4bytes and so we can have a maximum length of the field as 15, so maximum size of the header is 60 bytes out of which 20 bytes are mandatory.
The source IP address for an IPv4 datagram is stored where in the header?
4th longword (bytes 13-16)

The datagram length field in an IPv4 datagram contains which numeric value?
Total number of bytes in the datagram, including the header.The length of an IP datagram itself is technically measured in bytes. The length field represents the size of both the header and the data portions of the datagram.
IP ADDRESS occupies how many bytes?
IPv4 addresses are 4 bytes. IPv6 IP addresses are 16 bytes.
What is the size of today's standard (IPv4) IP address?
The size of an IPv4 address is 32 bits, or 4 bytes.
What is udp header?
8 bytes
How many bites does an IP address have?
In case of IPv4, the address has 4 bytes. In case of IPv6, the address has 16 bytes.
Which IPv4 header field is responsible for defining the priority of the packet?
differentiated services
What is the maximum allowable depth of a door header dent?
60 bytes out of which 20 bytes are mandatory
