Yes, that exactly the way we do it. If I imagine the power needed to implement this its nearly impossible to reimpleent for ONLY name-based Virtual Hosts. And if you think of Bandwith management - i don't see any way to do this on an per name-basis, only per ip (and service) is possible as far as I know. To use Bandwidth mangement on named vhosts-basis, you would have to read out the FULL ip-header and service-specific headers on the router...i think this is not possible without enormous CPU-power and would give high delays on the router. ------------------------------------------------ BS Web Services Roedingsmarkt 14 20459 Hamburg Germany info@bsmail.de www.bsws.de fon: +49 40 3750357-0 fax: +49 40 3750357-5 PLEASE USE EMAIL WHERE POSSIBLE Mark Lastdrager To: henning.brauer@bsmail.de <mark@pine.nl cc: Daniel Roesen <noc@entire-systems.com>, "lir-wg@ripe.net" <lir-wg@ripe.net> > Subject: Re: IP assignment for virtual webhosting 11.05.00 13:22 At Thu, 11 May 2000, owner-lir-wg@ripe.net wrote:

there is one big problem i see: If you charge your customers for traffic, you must count the traffic, and the easiest and most reliable way to do this is on the firewall/router. Thats the way we do and therefore we need one IP per customer. Most customers have more than one site and for that we are using HTTP 1.1 (NameVirtualHosts). As long as there is no Package for apache to count the traffic !reliable! (the traffic counted via access logs is << real traffic ) I do not see a way to put all customers to a couple of IPs.

Same over here. We have built our own database-driven system over the last years which links IP adresses to customers, measures their traffic and even has the ability to traffic-shape groups of IP adresses to a certain bandwith, like a Packeteer box can do. Input comes from the border router which has IP accounting. Ofcourse when customers want more than one hostname linked to the same virthost (but with different content) we use a name-based virthost. Because of this system it is very hard to implement name-based virtual hosting, all accounting is done on one IP adress then and we have to rethink our accounting scheme of virthosts (which takes time, costs money etc. etc.) Mark Lastdrager Pine Internet -- email: mark@lastdrager.nl :: ML1400-RIPE :: tel. +31-70-3111010 http://www.pine.nl :: RIPE RegID nl.pine :: fax. +31-70-3111011 PGP key ID 92BB81D1 :: Dutch security news @ http://security.nl Today's excuse: Dew on the telephone lines.
