I've done quite a bit of searching and can't seem to find a definitive answer to my problem.
I am periodically seeing errors where my code is doing an http get request to a web service which offers both IPv4 and IPv6 connectivity. My code is running in a docker container without IPv6 enabled on a machine that also doesn't have IPv6 enabled. Yet go is trying to connect to this website via IPv6 and I get a failure like dial tcp [XXXX:XXXX:XXXX:XXX::XXXa]:443: connect: cannot assign requested address. The error makes sense, IPv6 connections aren't going to work from this machine. The question is why is go even trying to connect via IPv6 when that isn't an option on the machine? I've gone through and read quite a bit about the Go resolver and confirmed it does request both the A and AAAA records for a domain name. This particular service advertises 8 different IPv4 addresses and 1 IPv6 address when I look at the returned address options. I want to make sure Go doesn't try the IPv6 address. Any suggestions on how I can keep Go from trying to use the IPv6 address or better yet have it not even query for the AAAA record? Most of the time I don't have problems but I'm seeing this error in my logs often enough that it is concerning. Thanks!
