What is DHCP in Wireshark?

DHCP is a client/server protocol used to dynamically assign IP-address parameters (and other things) to a DHCP client. It is implemented as an option of BOOTP. Some operating systems (including Windows 98 and later and Mac OS 8.5 and later) use APIPA to locally assign an IP-address if no DHCP server is available.

Is DHCPv6 the same as IPv6?

It is the IPv6 equivalent of the Dynamic Host Configuration Protocol for IPv4. DHCPv6 is defined by RFC 8415. Such routers require not only an IPv6 address for use in communicating with upstream routers, but also an IPv6 prefix for use in configuring devices on the downstream side of the router.

The way that Wireshark works is that the network packets coming to and from the network interface are duplicated and their copy is sent to the Wireshark. Wireshark does not have any capacity to stop them in any way – the original packets will still be processed by the operating system and consequently passed on to the processes and applications expecting them.

What is the use of Wireshark?

Wireshark is network monitoring and analyzing tool. You can use it to check different types of traffic going through your network, it details each packet and can read all OSI layers separately hence making troubleshooting very effective.
