[ale] apache question.. slightly OT

[Armsby John-G16665]

My appologies for being slightly off topic but.....


I am currently restricting access to my apache site by IP subnet.



    Order deny,allow
    Deny from all
    allow from 155.102 155.102.110 144.186.170 144.186.171 155.108.1 200.60.6 200.60.7 200.60.54 145.7.101 145.7.102 145.7.103 145.7.108 145.7.109 10.228.128 

The proliferation of subnets is going to eventually bury me.


I would like to restrict by domain name.  


Can someone tell me what I need to modify in the httpd.conf file to restrict access to everyone BUT "companyname.com"?


Thanks,




John
