My initial corruption was due to lack of accounting for that 1 index. Anyways, even when I accounted for it, I was getting the corruption, so I concluded that this lack of index was not the root cause of the corruption.

Static allocation has worked around the problem for now.

Two other problems I am facing now:

1) What I am having problem understanding is, why getaddrinfo() is not able to resolve if I give it the entire hostname, whereas leaving out the domain name gives me an error stating service name or host not found.

2) Some combinations of hosts(on the same domain) are unable to interconnect.

The scenario that occurs is,
Initially master waits for incoming connections, and when all clients have connected, passes each client its right neighbours details and instructs the client 1 to go ahead and connect to its right neighbour and then so on.
However, what I am seeing is, on some machines wherein master is on one machine, and clients on another, the Player 1 receives a connect refused(even though i traced the code of the other client and ensured it was listening.
So Master is on Host1
Client 1 and Client 2 on Host 2.
Client 2 listens on port 5555.(assume)
Client 1 tries to connect to neighbour on host 2 and port 5555.
It gets a connect::connection refused.

Output of actual Run

Server Output
-------------
./master 65450 2 10
packet Master on bn19****
clients = 2
Hops = 10
client 1 is on host nom2684*****
client 2 is on host nom2684*****
<Hangs at this point>

Client 1 Output
---------------

./client bn19****
Connected as client 1
Trying to connect to host nom2684**** on port 34437
connect:: Connection refused
<exits>

Client 2 Output
---------------

Connected as client 2
I am client 2 and I am listening on port 34437
I sent my port 34437 to master
<Hangs>
