According to resolv.conf(5) you can by default only configure 3 (!) name servers instead of the four you have. Also, it doesn't make sense to configure a nameserver to return its own host name, so I would consider your test case being invalid. The interesting question would be which name server answers for the case that you query some other host name (also since you said what you want those servers to do is caching, not authoritative name services). Since those are public IPs, I happened to positively check for the existence of a firewall. Its configuration regarding DNS queries (UDP _and_ -- always forgotten -- TCP port 53) would be interesting, esp. the configured allowed IP ranges for source and destination. -hwh -- gentoo-user@gentoo.org mailing list
