FTP-Data uses port 20.
If you want to communicate with systems on the local network, you will not need to configure a default gateway.
An IP address is made up of four 8-bit octets, which gives a total of 32 bits.
An IP address is made up of four 8-bit octets
A subnet mask of 255.255.255.0 means that the first three octets are part of the network ID and the last octet is the host ID portion of the address
Because the subnet mask is 255.255.0.0, the network ID of the IP address is 134.67.x.y—which means that anyone else with the same first two octets is on the same network
Class B networks support 65,534 hosts because the last two octets are the host ID and each octet supports 256 possible values. 256 × 256 = 65,536—but don’t forget there are two addresses that are unusable (the network ID and the broadcast address).
C. The default subnet mask of a class C network is 255.255.255.0, which means that the first three octets are the network ID and the last octet is the host ID.
The loopback address is typically known as the 127.0.0.1 address, but it could be any address starting with 127.x.y.z.
The port used by HTTP is port 80.
10.0.0.34 and 172.16.7.99 are examples of addresses that fall into the private IP address ranges, which are not routable on the Internet.
Port 25 is used by SMTP to send e-mail over a TCP/IP network.
126.96.36.199 is a class B address, so it has a subnet mask of 255.255.0.0.
. DHCP is responsible for assigning IP addresses to systems automatically so that the network administrator does not have to perform that job manually.
DNS is used to resolve FQDNs to IP addresses.
