What is a Public IP Address?
What is a Private IP Address?
What is a Default Gateway?
Default Gateway - is a the device that passes information from the local subnet to some other subnet (local network to internet)
In home, the home router is assigned the default gateway ip address - 192.168.1.1
What is a CIDR Notation?
First address of a network, followed by a slash character (/), and ending with the bit-length of the prefix. For example, 192.168.1.0/24 is the prefix of the Internet Protocol Version 4 network starting at the given address, having 24 bits allocated for the network prefix, and the remaining 8 bits reserved for host addressing
What is a Subnet?
The practice of dividing a network into two or more networks is called subnetting.
Subnets may be arranged logically in a hierarchical architecture, partitioning an organization’s network address space into a tree-like routing structure.
What is a Subnet Mask?
A subnet mask is a screen of numbers used for routing traffic within a subnet. Once a packet has arrived at an organization’s gateway or connection point with its unique network number, it can be routed to its destination within the organization’s internal gateways using the subnet number.
What is a DHCP Server?
Where is a DHCP Server located?
DHCP server is located in the Router. If you do ipconfig /all you will see any entry mentioning the DHCP entry.
Goto your browser and type the ip address of the DHCP Server -> it will take you to the router admin console
Most likely it will be the same as the default gateway.
What is a DNS Server?
Domain Name Servers (DNS) are the Internet’s equivalent of a phone book. They maintain a directory of domain names and translate them to Internet Protocol (IP) addresses. This is necessary because, although domain names are easy for people to remember, computers or machines, access websites based on IP addresses
Where is a DNS Server located?
DNS Server is a servics provided by the ISP - http://dns.comcast.net/
Some smart routers act as a local DNS Server by remembering ip addresses of a websites.
Command - ipconfig /all | findstr /R "DNS Servers"
What is a primary DNS?
