Shared Network

[Frank Bulk]

Every IPTV DHCP configuration I've seen uses classes that match against the
VCI (vendor class identifier)...I would recommend that approach instead of
the gateway IP.

Subject: Shared Network

I am useing ISC 4.1.0 and i am tring to set up my dhcpd.conf file. I work
for a IPTv provider and we are going to use it for our STB network. The STB
will request an ip address from the dhcpd server via 10.5.0.0/24 but we want
the STB to get 10.5.64.1-10.5.127.253 and we will be seting up 25 netorks
the same way. In our old dhcpd.conf file we set it up like the example below
and it will work on this dhcp server in this is the only class, shared
network and subnet set up on it. As soon as we add another network it will
pull address from the first one. We change the class name on each network
and match the allow statment in the ip pool to that class name. is there a
limit to how many shared networks you can add on a conf. file? If anyone has
a simular setup as we do can you send a example of how you did it. we have
about 5000 STB's that will pull a lease from this server so if there is a
better way of doing this please reply to this email.
