Re: Bad Dns address problem

This comes up about every week, please post details and let's see if we can find a pattern.

Carrier, url, etc. The DNS AFAIK is supposed to be provided by the carrier. I'm tempted to make only requests

based on IP and provide my own name server if I can get a host with a static IP address known to my application

( and have it lookup names using the DNS from its ISP).

 

Pattern to date is "port already bound" on ATT and whatever I posted earlier ( IIRC on Bloomberg url ) is from VZ.

 

I'm not entirely sure but I believe this is a silent-failure mechanism designed by carriers or others who provide competing

servers to degrade performance but I can't prove it. [ consider this a soliciation for opposing opinions, thanks ]
