# Frequently Asked Questions

### Q: Why do I get a "no such host" error resolving hostnames that other
|
|
programs can resolve?
|
|
|
|
Go uses a pure Go resolver by default for [name resolution](https://golang.org/pkg/net/#hdr-Name_Resolution).
|
|
This resolver behaves differently than the C library functions but is more
|
|
efficient when used with the Go runtime.
|
|
|
|
If you encounter problems or want to use more advanced name resolution methods
|
|
that are unsupported by the pure Go resolver, you can switch to the cgo
|
|
resolver.
|
|
|
|
If running manually set:
|
|
```
|
|
export GODEBUG=netdns=cgo
|
|
```
|
|
|
|
If running as a service add the environment variable to `/etc/default/telegraf`:
|
|
```
|
|
GODEBUG=netdns=cgo
|
|
```
