Smith: IMHO every dialup customer from every ISP in the world should use 192.168.254.1 for their DNS address and this number should be hard coded as the default in all client software. Then this problem would go away.if all ISPs agreed to use these addresses... say - TWO resolvers, e.g. 192.168.254,1 and 192.168.253.1 - two mail relays, e.g. 192.168.254.5 and 192.168.253.5 - two news servers, e.g. ---254.9 and 253.9 - two ntp time servers - etc etc [the addresses chosen for /30 netmasks, I think that in my Monday morning brain-state I got it right?] And so on for "standard" services, then we could achieve global roaming SO easily. The number of times we've had customers roam elsewhere and then try and use ou r mail relays when for spam reasons relaying is denied...After several discussions, we came up with this solution that we think works well to support standard services for roaming users: Support a .local. root domain in your DNS servers. Examples of DNS hostnames would be mail.local., ntp.local., news.local., etc. When a roamer dials up he generally uses the DNS servers assigned by the NAS; these addresses would be authoritative on a provider-by-provider basis. If all networks supported this schema all users could simply have these addresses coded into their client software and would connect to the proper machines as they differ on various networks. iPass is currently building an Internet-Draft specifying the details of this approach. What do you think? --Michael
That doesn't work; too many of those things must be hard-coded numbers (specifically, the DNS servers). .LOCAL along with defined addresses, declared as "non-routable" (ie: local only) *DOES* do the trick. -- -- Karl Denninger (karl () MCS Net)| MCSNet - Serving Chicagoland and Wisconsin http://www.mcs.net/ | T1's from $600 monthly / All Lines K56Flex/DOV | NEW!
