Resolv mistery

[bob83]

If i remove /etc/resolv.conf, restart server, i still can dig any unique domain.
How is that possible, how does my vps gets the ip by domain?

Are nameservers in etc/resolv.conf cached somewhere?

resolv.conf is automatically created on Virtuozzo VPSes so if your VPS is on that platform then it may be why this is happening.

Also I would not be terribly surprised to find that if resolv.conf does not exist then Linux might default to 127.0.0.1 ...

Also see which DNS server is shown when you dig.

e.g.

Code: Select all

;; Query time: 44 msec
;; SERVER: 208.67.220.220#53(208.67.220.220)
;; WHEN: Thu Jan 13 23:47:52 2011
;; MSG SIZE  rcvd: 48

Why would you remove the resolv.conf ? How would this help you in any way ?
