As for the part of my final year project I want to get a list of IP addresses of all the active routers in the network so that I can obtain it IPv6 status via getaddrinfo with the AI_ADDRCONFIG flag.

The current implementation of getaddrinfo works with 1 IP at a time and I need to change the IP from the source each time need to check another one. My aim is to create a list of IP address of active routers and parse the IP addresses to the getaddrinfo method.

I would be really grateful if you experts would point me to any references or provide any sample code segments to get all the IP addresses of active routers within a network.

PS: I found similar posts (Find out IP of all active machines on network) on this topic in stackoverflow but these did not help me as they were for java and android and slightly off topic than mine ().

Although the question you linked is tagged [tag:java], the answers are fairly language agnostic. – Olaf Dietsche Mar 27 '14 at 21:27
@OlafDietsche Thank you for the reply sir..I was trying to figure out but I am kinda new to this and thats one of the reasons I turned to you experts :) – Hasitha Shan Mar 28 '14 at 05:59
The first answer does a ping only. But it makes a broadcast, so every machine on the LAN answers. – Olaf Dietsche Mar 28 '14 at 07:44
@OlafDietsche the first answer? – Hasitha Shan Mar 28 '14 at 08:57
Sorry, it depends on your ordering of course. But there is only one answer using ping and the main point is anyway, that it uses a broadcast to detect all machines on the local net. – Olaf Dietsche Mar 28 '14 at 09:54
@OlafDietsche thank you very much for your support sir..i will check more on your suggestion :) – Hasitha Shan Mar 28 '14 at 09:58
