Internet Protocol is a set of technical rules that defines how computers communicate over a network. There are currently two versions: IP version 4 (IPv4) and IP version 6 (IPv6). IPv4 was the first version of Internet Protocol to be widely used, and accounts for most of today’s Internet traffic. There are just over 4 billion IPv4 addresses. While that is a lot of IP addresses, it is not enough to last forever. IPv6 is a newer numbering system that provides a much larger address pool than IPv4

How To Convert a Wireless Router into an Access Point Linksys WRT54G Step 1: Connect a computer that is set to obtain its IP address information automatically to a LAN port on the wireless router that you want to convert to an AP. If you don't know how to do this, Figure 1 shows the applicable Windows XP screens. (Get to the Network Connections window by Start > Settings > Network Connections.)

groups, such as All Hosts on the local network or All Routers on the local network. In IPv6 all nodes are required to support multicast. Without multicast, many services that you need will simply not work. There’s a constant hum from the network on the multicast channels. When IPv4 was specified about 30 years ago, there was no multicast standard for IP networks initially. A lot of network services, like DHCP and ARP, had to depend on broadcast to work. IPv6 is a new protocol and had multicast services

in case you see an address like mail.subdomain.company.com, you can easily recognize the name of the system (mail), name of the sub-domain (sub-domain), name of the company (company) and the name of the primary domain (.com). DHCP – Dynamic Host Control Protocol A DHCP server automatically assigns the IP addresses for a device. Any device, before communicating with any other device in the network needs an IP address. These IP addresses are given to the network devices dynamically by a DHCP server

What to do if a customer needs a static IP loaded onto gateway 1. Check in billing to see if the rate code is there - In ACSR “CCO Static IP 1” (or 5, 13) will be used as the code - In DST select their IP Gateway by going to “Change box data” (11), note the rate codes (UH 1, @5 1, e.g.) then hit F5 to open up the window where you can check rates, hit 5 and enter and scroll through to verify there is a static IP on the account; if none found—transfer

one mask provide enough host IP addresses to support the largest subnet. Doing so the number of host bits (H) defined by the mask must be large enough so the 2h-2 is larger than or equal to the number of host IP addresses required in the largest subnet. To accommodate the growing subnet you will need at least 8 host bits. Eight host bits would be enough because 28-2=254 and 7 host bits will not be enough (27=126). 2^8-2=254 will support more than enough for 145 more host and with the growth of the

com would appear. Computers use numerical IP addresses to translate “Google.com”. Google’s IP address is 173.194.39.78 and if you were to type this in the address bar the website would populate this way as well. DHCP stands for “Dynamic Host Control Protocol” and is used to automatically assign IP addresses to authorized computers attempting a connection to the network. The way this works is that a computer attempting a connection will send a request to the DHCP server. The server receives

DNS and DHCP DNS is short for Domain Name System servers, and they provide name resolution for network clients. Among other things, DNS manages information that connects a computer's fully qualified domain name or FQDN to its assigned IP address. Sometimes, DNS links them to multiple addresses.On the other hand, DHCP provides a powerful mechanism for automatically configuring client IP addresses. At first, DHCP did not notify the DNS service to update the DNS records on the client. They

This is very important. If you don't provide the calculations or the way you get the answer, you will lose 50%. Your goal is to subnet them with as little subnet as possible but still meeting the requirement. In other word, maximize the number of hosts that is available for each subnet. 26. 134.84.0.0/16 subnetted to 97 subnets and provide information for subnets #1, #8, #65, and #97 134.84.0.0/16 10000110 01010100 00000000 00000000 Network address 11111111 11111111 00000000 00000000
