DHCP is used for automatically configuring devices that join a TCP/IP-based network. This configuration can include elements such as an IP address, subnet mask, DNS server addresses, a default gateway address, and other configuration information.
Which tool automatically assigns an IP address whenever a computer connects to the network group of answer choices?
DHCP definition
DHCP stands for dynamic host configuration protocol and is a network protocol used on IP networks where a DHCP server automatically assigns an IP address and other information to each host on the network so they can communicate efficiently with other endpoints.
Which tool is used by an administrator to manage many routers and obtain an overall view of all the routers?
Which tool is used by an administrator to manage many routers and obtain an overall view of all the routers? Secure Shell (SSH) is a terminal emulation program that uses the network to connect routers.
Which formula would you use to arrive at the number of hosts on a subnet?
Remember that the formula for determining the number of hosts a network supports is 2n-2, where n is the number of bits used for the host. The /28 is CIDR notation indicating that 28 bits are used for the subnet mask. An IPv4 address includes a total of 32 bits.
Which unit is used to measure signal loss in networking?
Attenuation is the loss of signal strength in networking cables or connections. This typically is measured in decibels (dB) or voltage and can occur due to a variety of factors.
What is IPv6 vs IPv4?
IPv4 is 32-Bit IP address whereas IPv6 is a 128-Bit IP address. IPv4 is a numeric addressing method whereas IPv6 is an alphanumeric addressing method.IPv4 offers 12 header fields whereas IPv6 offers 8 header fields. IPv4 supports broadcast whereas IPv6 doesn’t support broadcast.
What is DNS used for?
The Domain Name System (DNS) turns domain names into IP addresses, which browsers use to load internet pages. Every device connected to the internet has its own IP address, which is used by other devices to locate the device.
Which tool is used by an administrator to manage many routers?
Traceroute The traceroute command is used to determine the path between two connections. Often a connection to another device will have to go through multiple routers. The traceroute command will return the names or IP addresses of all the routers between two devices.
Which of the following automatically gives out IP information to computers that request it?
In this scenario, you are the DHCP clientwhenever you want to go on the Internet, your computer automatically requests an IP address from the network’s DHCP server. If there’s one available, the DHCP server sends a response containing an IP address to your computer.
What tool can you use to discover the IP address of a client’s NIC?
4: Advanced IP Scanner
Advanced IP Scanner (Figure D) is a free tool for scanning an IP address range to collect network device data.
Which IP address is a public IP address?
A public IP address is an IP address that can be accessed directly over the internet and is assigned to your network router by your internet service provider (ISP). Your personal device also has a private IP that remains hidden when you connect to the internet through your router’s public IP.
How do I find a broadcast address from an IP address?
Another short cut for broadcast address calculation after getting netwotk address is:
- calculate total no of hosts (in this case it is 2^12 = 4096)
- Divide it by 256(in this case it is 16) and add the result – 1(in this case 15) in *corresponding octet(in this case second octet i.e. 32+15=47) and make other octet 255.
How is IP calculated from Netmask?
To calculate the IP Address Subnet you need to perform a bit-wise AND operation (1+1=1, 1+0 or 0+1 =0, 0+0=0) on the host IP address and subnet mask. The result is the subnet address in which the host is situated.
What is insertion loss testing?
Insertion loss measurement is one of the critical measurements used to analyze transmission feed line installation and performance quality.Insertion loss measures the energy absorbed by the transmission line in the direction of the signal path in dB/meter or dB/feet.
What is insertion loss RF?
Editorial Team – everything RF
Whenever a signal travels through a component or a system, there is always some loss of power due to a number of reasons. This loss that occurs while a signal is traveling through a component or system is called as Insertion Loss. It is measured in decibels (dB).
What causes insertion loss?
Excessive length is the most common reason for failing insertion loss. Fixing links that have failed insertion loss normally involves reducing the length of the cabling by removing any slack in the cable run. Excessive insertion loss can also be caused by poorly terminated connectors / plugs.
What is IPv6 connection?
Internet Protocol Version 6 (IPv6) is a network layer protocol which allows communication and data transfers to take place over the network.With wireless and network-attached devices increasing rapidly by the day, the internet will exhaust all unique IPv4 addresses at some point.
What is IPv6 address?
An IPv6 address is a 128-bit alphanumeric value that identifies an endpoint device in an Internet Protocol Version 6 (IPv6) network. IPv6 is the successor to a previous addressing infrastructure, IPv4, which had limitations IPv6 was designed to overcome.
What is IPv6 in networking?
Internet Protocol version 6 (IPv6) is the most recent version of the Internet Protocol (IP), the communications protocol that provides an identification and location system for computers on networks and routes traffic across the Internet.IPv6 is intended to replace IPv4.
How do I assign an IP address to a domain?
- Go to your webhost site.
- Open Control Panel Login and log into it as the account admin.
- Select Technical Contact.
- Go to Domain Name Administration.
- Click DNS Administration.
- Select the domain you want to point to a new IP.
- Type in your new IP address.
- Update.
