The pure Go resolver will now use EDNS(0) to include a suggested
|
|
|
|
maximum reply packet length, permitting reply packets to contain
|
|
|
|
up to 1232 bytes (the previous maximum was 512).
|
|
|
|
In the unlikely event that this causes problems with a local DNS
|
|
|
|
resolver, setting the environment variable
|
|
|
|
<code>GODEBUG=netdns=cgo</code> to use the cgo-based resolver
|
|
|
|
should work.
|
|
|
|
Please report any such problems on <a href="/issue/new">the
|
|
|
|
issue tracker</a>.
