Hi Bruce Thank you so much to explain me in detail. I would like to know about this it in case i can get another hosting company
Yes. I think the netmask should be 255.255.255.255 1/ but why they are using this netmask setting? save ip address? then does the router handle many routes in this setting? 2/ What is this advantage for the hosting company? 3/ If I need more ip in the same server, how it works? 4/ Why you said the hosting company is cheap to use this configuration? Thank you again. > > <SNIP> > 2/ lf the network card in server has problem and need change another > one, will my ip address change to another ip address also? > </SNIP> > Yeah well thats how dhcp works, via ma caddy, i guess you can always spoof > your old mac address. > > <SNIP> > 3/ why hosting company is using /32 and dhcp? what is advantage? ls it > easy for administration? > </SNIP> > Im guessing because the users are to stupid to understand what a subnet > mask/gateway is its just easier to get the mac address and assign it to a > user then let the user assign a ip. > > > Normally in a co-location setup its not like this, inless its very cheap > hosting. > > My co-location has the following setup, and this is how MOST networks should > be run. > > Core router using BGP to transit providers, and other local peers. > Switched network useing ospf to handle the routes and also VLAN's for the > customers subnets. > > So customer should get a vlan assigned to them (which they have no need to > know what the number is, they are handed a access mode port. > Customers also issued a /30 (at least) in most cases a customer will get a > /29 or /28 depending on what they need. > In this case of a /30 its a total of 3 address's > 1, GATEWAY (put on the ISP/HOST switch > 2, IP ADDRESS FOR SERVER TO USE > 3, BROADCAST ADDRESS. > > Heres an eg of a /30: > > Address: 192.168.1.1 11000000.10101000.00000001.000000 01 > Netmask: 255.255.255.252 = 30 11111111.11111111.11111111.111111 00 > Wildcard: 0.0.0.3 00000000.00000000.00000000.000000 11 > => > Network: 192.168.1.0/30 11000000.10101000.00000001.000000 00 > HostMin: 192.168.1.1 11000000.10101000.00000001.000000 01 > HostMax: 192.168.1.2 11000000.10101000.00000001.000000 10 > Broadcast: 192.168.1.3 11000000.10101000.00000001.000000 11 > Hosts/Net: 2 Class C, Private Internet > > > Heres an eg of a /29: > > the % ipcalc 192.168.1.1/29 > Address: 192.168.1.1 11000000.10101000.00000001.00000 001 > Netmask: 255.255.255.248 = 29 11111111.11111111.11111111.11111 000 > Wildcard: 0.0.0.7 00000000.00000000.00000000.00000 111 > => > Network: 192.168.1.0/29 11000000.10101000.00000001.00000 000 > HostMin: 192.168.1.1 11000000.10101000.00000001.00000 001 > HostMax: 192.168.1.6 11000000.10101000.00000001.00000 110 > Broadcast: 192.168.1.7 11000000.10101000.00000001.00000 111 > Hosts/Net: 6 Class C, Private Internet > > Hope this makes sence. > > Regards, > > Bruce > > >
