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.


Why does the TCP header have a header length field and UDP header does not?

in tcp header (32 bits) we have a field that is called options and padding that has variable in length and the header length shows the actual header size i.e size of 20 octets+size of options and padding field and in UDP we dont have any field like that and its header is fixed of 8 OCTETS (32 bits header size) refrence: WIRELESS COMMUNICATIONS AND NETWORKS by William Stallings Second Edition pg 91(see fig)

How do you redirect a url in php?

URL redirects occur when the server, ran by PHP, gives the client a new location to be at. This information is sent using a the HTTP Location header.Such a header can be sent using the header($str) function, where $strequals "Location: http://www.example.com/". This would send the client to example.com.Although uncommon, browsers can be configured to ignore location headers. Do not assume the client will always be redirected.

What information can I find in the garage door header size chart?

A garage door header size chart provides information on the recommended size of the header beam needed to support a garage door. This chart helps determine the appropriate header size based on the width of the garage door opening and the type of construction materials used.


Can you provide information on how to properly install a wall header in a load-bearing wall?

To properly install a wall header in a load-bearing wall, you need to first determine the size of the header required based on the span and load it will support. Next, you will need to remove the existing studs where the header will be placed and install the header using appropriate fasteners and support. It is important to follow building codes and consult with a structural engineer if needed to ensure the header is installed correctly and safely.


Why is it that a server needs a fixed port number but client process can be given any random port number?

The client process needs a temporary port number. It tells the server to which port to reply (the TCP or UDP header includes information about the source and the destination port). The client, on the other hand, doesn't know in advance what port the server uses - unless the server uses a standard port number.The client process needs a temporary port number.
