Weather dhcp offer is unicast or not?

The answer is yes. The RFC 1541 states that a server "should" try unicast first, but then can use broadcast when offering. Some OS's like Microsoft skip the unicast part of this as it is not required. I would like to improve upon this answer As i see in RFC 1541, server would try to unicast DHCP offer in case it has received DHCP Discover from a DHCP relay agent otherwise it would broadcast. Would like to know if anybody differ in opinion....


What is the purpose of bgp?

The Border Gateway Protocol (BGP) is the core routing protocol of the Internet. It maintains a table of IP networks or 'prefixes' which designate network reachability among autonomous systems (AS). It is described as a path vector protocol. BGP does not use traditional IGP metrics, but makes routing decisions based on path, network policies and/or rulesets. BGP was created to replace the EGP routing protocol to allow fully decentralized routing in order to allow the removal of the NSFNet Internet backbone network. This allowed the Internet to become a truly decentralized system. Since 1994, version four of the protocol has been in use on the Internet. All previous versions are now obsolete. The major enhancement in version 4 was support of Classless Inter-Domain Routing and use of route aggregation to decrease the size of routing tables. Since January 2006, version 4 is codified in RFC 4271, which went through well over 20 drafts based on the earlierRFC 1771 version 4. The RFC 4271 version corrected a number of errors, clarified ambiguities, and also brought the RFC much closer to industry practices. Most Internet users do not use BGP directly. However, since most Internet service providers must use BGP to establish routing between one another (especially if they aremultihomed), it is one of the most important protocols of the Internet. Compare this withSignalling System 7 (SS7), which is the inter-provider core call setup protocol on thePSTN. Very large private IP networks use BGP internally, however. An example would be the joining of a number of large Open Shortest Path First (OSPF) networks where OSPF by itself would not scale to size. Another reason to use BGP is multihoming a network for better redundancy either to multiple access points of a single ISP (RFC 1998) or to multiple ISPs.


What is the formula for the atomic number?

atomic number = number of proton in an element number of proton = number of electron mass number = number of proton + number of neutron therefore... atomic number = mass number - number of neutrons

How do you get the mass number by adding neutrons and the atomic number?

mass number = number of protons + number of neutrons The atomic number is equivalent to number of protons.
