A single IP_ADDRANY-bound UDP server should be able to appear to respond on the same dynamically-assigned IP address a packet is received on. Luckily, there is another way. Depending on … Read more

TCP – difference between Congestion window and Receive window
To give a short answer: the receive window is managed by the receiver, who sends out window sizes to the sender. The window sizes announce the number of bytes still free in the receiver buffer, i.e. the number of bytes the sender can still send without needing an acknowledgement from the receiver. The congestion window … Read more

Get local IP-Address without connecting to the internet
fe80:0:0:0:226:4aff:fe0d:592e is your ipv6 address ;-). Check this using if (current_addr instanceof Inet4Address) System.out.println(current_addr.getHostAddress()); else if (current_addr instanceof Inet6Address) System.out.println(current_addr.getHostAddress()); If you just care for IPv4, then just discard the IPv6 case. But beware, IPv6 is the future ^^. P.S.: Check if some of your breaks should have been continues.
