Service httpd error

I have a centOS virtual machine with 3 virtual hosts. It worked fine until this moment when I lost access to the dns server. Now the hosts can't be resolved. Can any1 tell me if I can configure some static routes or something to the virtual hosts?

Print screen with the httpd response:

P.S. I would prefere not to configure a DNS ser开发者_开发知识库ver since the old one will start tomorrow again.

In your /etc/hosts you can map IP addresses to hostnames:

127.0.0.1 example.com
127.0.0.1 example.net
// etc...
