Hi All,
I see that Resiprocate uses the Asynchronous DNS.
Use Case: A(resiprocate stack) calls B (SIPP) I have DNS configured with the hostname b.com. (resolve.conf has 3 DNS servers).
When A calls B (b.com), I see that because of Asynchronous DNS (as mentioned in the Documentation) Before sending to B, stack does a FORK for A record with b.com. (3 queries to 3 DNS servers) call is getting established.
But in TCP dump I could see that that there are 9 more queries.(which is 3 ‘A’ requests to 3 DNS)
> How many Queries that the stack do the above case. if so at what places. From Application I can see that only one Lookup is being done…
> is there any documentation for this that can help me...regarding DNS queries
TIA J SReeram |
