[zen37]

Yes (sorry, this is a very insignificant issue, but I could not help it to raise it)

What operating system and processor architecture are you using (go env)?

go env Output

$ go env

What did you do?

https://cs.opensource.google/go/go/+/refs/tags/go1.19.4:src/net/dnsconfig.go

What did you expect to see?

attempts      int           // number of tries before giving up on a query

What did you see instead?

attempts      int           // lost packets before giving up on server

[mateusz834]

attempts      int           // number of tries before giving up on a query

This is not true either.

go/src/net/dnsclient_unix.go

Lines 273 to 275 in f721fa3

	for i := 0; i < cfg.attempts; i++ {
	for j := uint32(0); j < sLen; j++ {
	server := cfg.servers[(serverOffset+j)%sLen]

total attempts is equal to: len(servers) * attempts
