How Much Space Do I Need as an ISP?

[Samuel Mwamsaku]

Use the lookup table to estimate how many bits are required at each level to get the right prefix length of the address

[Harry Kumwenda]

Can some assist on how much space do I need as an ISP? I’m lost on the procedure how to find number of number.

Thanks in advance

Try use 52 prefix ( 52 – ( Cities Bits + Housing Estates + Housing Units ) )

[Stephen Olude]

I now know how to plan for my IPV6

log(expected value)/lo(2) = x

the number of space to each home network j – number of POP i- number of estate e on each pop – number of housing unit u on each housing estate = required subnet /y (j – i – e – u =/y).

Should traffic for every device to be separated by different VLANs? i suppose we need millions vlans at some point

[samson Mawisire]

its going to depend current situation and also provision for growth. Typically a /32

[Dersio Jason IE SAIO SA]

but why we dont have 50 instead of 72

[Jonas Ababio]

Assigning a /60 to a housing unit gives room for 16 * /64 subnets == 16 different VLANs which is enough for a home.🤔

As an ISP with a <b data-path-to-node=”8,0,0″ data-index-in-node=”31″>/32 allocation, if you decide to give every single customer a <b data-path-to-node=”8,0,0″ data-index-in-node=”93″>/56 prefix instead of a <b data-path-to-node=”8,0,0″ data-index-in-node=”117″>/48, how many more customers can you support?
