Re: [Cable] Toronto Outage Check-ins The problem apparently is that Rogers not only allocates on a per head end POI basis, but on a CMTS basis. We've noted that at a given head end, there is now 1 POI router per POI connection to TekSavvy. They are apparently simply not moving the available IPs to cover new CMTS units. Now it may be that the POI router is fed from selected CMTS units which is also causing some division of IPs problems, but the bottom line is the screwy way they are allocating IPs.
said by sbrook:TTBOMK, hierarchical subnetting is a perfectly legitimate networking practice... simple and efficient routing at the expense of address space. Facilitating this is one of the main reasons why IPv6 went overkill with 128bits.
