UDP is connectionless, meaning that no virtual circuits are required during data transmission between hosts. The connectionless feature of UDP6 enables it to send data to multicast addresses. This is different from TCP6, which requires specific source and destination addresses. RawIP6 RawIP6 fills ...

In IPv6, you are allowed to remove leading zeros, and then remove consecutive zeros, meaning ::ffff: actually translates to 0000:0000:ffff:0000, this address has been designated as the IPv4 to IPv6 subnet prefix, so any IPv6 processor will understand it's working with an IPv4 address a...
The address 255.255.255.255 is used as broadcast addresses and 0.0.0.0 as a default route address, meaning any network. The address 0.0.0.0 is sometimes used by hosts that have yet to receive an IP address e.g. a DHCP Client awaiting an address from the DHCP server. ...
(254 hosts each and not 256 because there are two prohibited hostid patterns: all zeros is reserved to refer to the network itself in routing tables, and all ones is the broadcast address meaning "all hosts on this network") Several years ago I did a lot of consulting work for ...
A symbolic Tag is assumed, but an @ indicates a numeric CIP address, with each segment’s meaning defaulting to: @<class>/<instance>/<attribute>/<element> More complex non-default numeric addressing is also supported, allowing access to Assembly instances, Connections, etc. For example, to...
For example, 10.*.1, 192.168.*, 127.*, and *224* are all valid uses of the asterisk wildcard. Using an invalid combination of a destination and subnet mask (netmask) value displays a "Route: bad gateway address netmask" error message. This error message appears when the destination ...
When used as a destination, only address 0.0.0.0 has meaning, and then only to the local machine as referring to itself, or as a convention to refer to a default route. n Loopback network address 127—As noted under Class A addresses, network address 127 is not used as part of a ...
To use UDP, an application must supply the IP address and UDP port number of the destination application. A port provides a location for sending messages. A port functions as a multiplexed message queue, meaning that it can receive multiple messages at a time. Each port is identified by a ...
