Internet group management protocol (IGMP) will be the best model to use for the setting with six different locations. Each location organized using two subnets with each of them having static IPv4. Hosts ought to join the group by contacting their routers so as to get data from the multicast group. With this model, the host will be able to receive messages and data sent to the group addresses in spite of the source address of the sender. IGMP is used by hosts for announcing their interest to receive a multicast group to edge routers. To take part in IP multicasting, multiplayer switches, routers, and multicast hosts ought to have the IGMP operating. This protocol gives a definition for the hosts together with querier.
Host is the receiver sending report messages for informing a querier of the membership of the host. Querier a network device for sending query messages for discovery which network devices are members of a certain multicast group. The IPv4 should be administratively scoped to ensure security of the shared crucial information. The DNS for alpha company alpha will be alpha.com. This will enable users to go to the website without knowing the IP address of the user. It will also enable the computer to locate the website based on its IP address. It is dependable for appropriately routing the mail server that processes an email address (Kumar, et al 1998).
Internet protocol (IP) addresses are internet locations for identifying a unique computer or local area network. Reverse lookup will give the user information concerning the IP address. It will state the computer name and the network it is using. Reverse lookup of IP can be performed by use of reverse lookup tools that are found on the internet. Domain name system (DNS) is an essential internet networking aspect, since it is responsible for matching of domain names, to IP address of the web servers hosting these domain names. The host record is located in the forward lookup zones, DNS folder matching a domain or computer to the IP address. The pointer record is located at the Reverse Lookup zones folders matching the IP address to the computer name or domain. An internal DNS reverse lookup implies that it ought to be done inside a network with the IP address (Kumar, et al 1998).
Installation of redundant DNS infrastructure will be prioritized in the organization due to various reasons. This infrastructure has an unbeatable uptime. It ensures a fast and reliable resolution is served with the highest uptime. It ensures there is maximum protection against failure of server and has an impressive uptime network. This infrastructure also has an increased security and capacity. The infrastructure is based on increased security and has extremely adaptable server capacity with a structure that has the capability supporting management of many domain names. It has a total control of the DNS zones. With master/slave redundancy, a change in the zone file leads to automatic propagation to the slave servers. There is a high speed due to numerous reasons like reduction of latency and fast connection.
To ensure there is security of the crucial information exchanged, the database and web servers should be separated from the database. For the protection of data in integration service packages, one can set a protection level for helping protection of just sensitive data or all the package data. The data can also be encrypted with a password or a user keyword (Cain, 1999).
