- Use a DNS service that uses Anycast for their servers
- Make sure the DNS provider has servers distributed globally (and that perform well)
- Try to avoid long CNAME chains (try to avoid them at all if possible)
- Use a long Time To Live (TTL) on your records so they can be cached by the ISPs and users
From mentioned about I think that most effective is focus on 2nd option. My server is in Praque, my domain registrar (eNOM) is in US. I was not able to find if they use some kind of distributed DNS (SE Asia region has too long DNS look up).

I found out that Cloudflare has free globally distributed DNS network.
