2. Wildcard mask - Wikipedia

   en.wikipedia.org/wiki/Wildcard_mask

   A wildcard mask is a mask of bits that indicates which parts of an IP address are available for examination. In the Cisco IOS, [1] they are used in several places, for example:

3. List of TCP and UDP port numbers - Wikipedia

   en.wikipedia.org/wiki/List_of_TCP_and_UDP_port...

   This is a list of TCP and UDP port numbers used by protocols for operation of network applications. The (TCP) and the (UDP) only need one for , bidirectional traffic. They usually use port numbers that match the services of the corresponding TCP or UDP implementation, if they exist.

4. IP address - Wikipedia

   en.wikipedia.org/wiki/IP_address

   All receivers capture the network packet. The address 255.255.255.255 is used for network broadcast. In addition, a more limited directed broadcast uses the all-ones host address with the network prefix. For example, the destination address used for directed broadcast to devices on the network 192.0.2.0 / 24 is 192.0.2.255. [24]

5. Comma-separated values - Wikipedia

   en.wikipedia.org/wiki/Comma-separated_values

   CSV is a delimited text file that uses a comma to separate values (many implementations of CSV import/export tools allow other separators to be used; for example, the use of a "Sep=^" row as the first row in the *.csv file will cause Excel to open the file expecting caret "^" to be the separator instead of comma ","). Simple CSV implementations ...

7. Broadcast address - Wikipedia

   en.wikipedia.org/wiki/Broadcast_address

   A special definition exists for the IP address 255.255.255.255. It is the broadcast address of the zero network or 0.0.0.0, which in Internet Protocol standards stands for this network, i.e. the local network. Transmission to this address is limited by definition, in that it is never forwarded by the routers connecting the local network to ...

8. Subnet - Wikipedia

   en.wikipedia.org/wiki/Subnet

   The routing prefix of an address is identified by the subnet mask, written in the same form used for IP addresses. For example, the subnet mask for a routing prefix that is composed of the most-significant 24 bits of an IPv4 address is written as 255.255.255.0.

9. Mask (computing) - Wikipedia

   en.wikipedia.org/wiki/Mask_(computing)

   In computer science, a mask or bitmask is data that is used for bitwise operations, particularly in a bit field.Using a mask, multiple bits in a byte, nibble, word, etc. can be set either on or off, or inverted from on to off (or vice versa) in a single bitwise operation.
