::ffff: is a subnet prefix for IPv4 (32 bit) addresses that are placed inside an IPv6 (128 bit) space. IPv6 is broken into two parts, the subnet prefix, and the interface suffix. Each one is 64 bits long, or, 4 groups of 4 hexadecimal characters.

255.0 ; A subnet declaration is required for every network your DHCP server is serving. Multiple subnets require multiple subnet declarations. If the DHCP server does not have a network interface in a range of a subnet declaration, the DHCP server does not serve that network.

In computer networks, a DMZ (demilitarized zone), also sometimes known as a perimeter network or a screened subnetwork, is a physical or logical subnet that separates an internal local area network (LAN) from other untrusted networks -- usually the public internet.

In Windows it requires the command prompt. Search for "cmd" (without the quotes) using Windows search. In the resulting pop-up box, type "ipconfig" (no quote marks). What is revealed is more than just the IP address: you'll see the IPv4 Address, the subnet mask, plus the Default Gateway (that's your router).

The subnet mask for any network where the first three numbers are the same is 255.255. 255.0. The 255 means that that part of the IP address is part of the subnet, the 0 means that it is not. ... The subnet mask comes into play both when defining the IP address for the router and when defining the DHCP range (more below).

A fixed-length subnet mask (FLSM) is a sequence of numbers of unchanging length that streamlines packet routing within the subnets of a proprietary network. A subnet can be a geographically defined local area network (LAN).

After all, most of us think in terms of IP addresses, not MAC addresses. Both subnets would then reside in VLAN 300. ... Takeaway: Your switches won't warn you if you have multiple subnets using a single VLAN. Never assume a VLAN has only one subnet.

Netmask and subnet mask are often used as if they're the same thing, but subnet masks are mostly used in network configurations, while netmasks often refer to classes of IP addresses. They're used to define a range of IP addresses that an ISP or other organization can use.

Dynamic Host Configuration Protocol (DHCP) automatically assigns IP addresses and other network configuration information (subnetmask, broadcast address, etc) to computers on a network. A client configured for DHCP will send out a broadcast request to the DHCP server requesting an address.

VLSM (Variable length subnet masking) is dividing IP into subnet with different sizes but FLSM (Fixed length subnet mask) is dividing IP into subnet with same range.

But it's technically valid. Takeaway: Your switches won't warn you if you have multiple subnets using a single VLAN. Never assume a VLAN has only one subnet. When in doubt, do a show run interface Vlan300 on your layer-3 switches to view both the primary and secondary IPs.

Calculating the maximum possible number of hosts in a subnet: To find the maximum number of hosts, look at the number of binary bits in the host number above. The easiest way to do this is to subtract the netmask length from 32 (number of bits in an IPv4 address). This gives you the number of host bits in the address.
