In addition, information on hosts which have successfully completed a DHCP transaction is accrued in a database of bindings which may then be used by other security or accounting features. [2] [3] Other features may use DHCP snooping database information to ensure IP integrity on a Layer 2 switched domain. This information enables a network to:
The DHCP server permanently assigns an IP address to a requesting client from a range defined by an administrator. This is like dynamic allocation, but the DHCP server keeps a table of past IP address assignments, so that it can preferentially assign to a client the same IP address that the client previously had. Manual allocation
This is a list of the IP protocol numbers found in the field Protocol of the IPv4 header and the Next Header field of the IPv6 header. It is an identifier for the encapsulated protocol and determines the layout of the data that immediately follows the header.
Returns a Response with variable binding for the lexicographically next variable in the MIB. The entire MIB of an agent can be walked by iterative application of GetNextRequest starting at OID 0. Rows of a table can be read by specifying column OIDs in the variable bindings of the request. GetBulkRequest
Show which processes are using which sockets (similar to -b under Windows) (you must be root to do this) No No Yes -P protocol: Shows connections for the protocol specified by protocol. In this case, protocol can be ip, ipv6, icmp, icmpv6, igmp, udp, tcp, or rawip. No No Yes -r: Displays the contents of the IP routing table.
The principal packet structure of ARP packets is shown in the following table which illustrates the case of IPv4 networks running on Ethernet. In this scenario, the packet has 48-bit fields for the sender hardware address (SHA) and target hardware address (THA), and 32-bit fields for the corresponding sender and target protocol addresses (SPA ...
DHCPv6 can provide this information whether it is being used to assign IP addresses or not. DHCPv6 can provide host with the addresses of Domain Name System (DNS) servers, but they can also be provided through Neighbor Discovery Protocol , which is the mechanism for stateless autoconfiguration.
A routing table is a data file in RAM that is used to store route information about directly connected and remote networks. Nodes can also share the contents of their routing table with other nodes. The primary function of a router is to forward a packet toward its destination network, which is the destination IP address of the packet.
