For a small customer why not just build redundancy with your ISP? Eg 2x circuits with two different access providers, BGP with a private ASN to two different routers at the ISP side. Outages tend to affect a particular router/BRAS/access handover so by making that redundant you're achieving "pretty good" redundancy.

Not sure if I am correct here but if they are using a /28 now to comply with the APNIC rules as per the below they would need to show use for 25% now (a /26) and within one year using a /25 (50% of address space).


It may be that APNIC may let them be a bit fuzzy about the exact number �in use� but the rules would seem to exclude them as they would need to quadruple their use of IP Addressing /28 to /26 immediately.

Again - not an APNIC rules expert and I could be wrong here.

A "small company wanting to play big company" question:
My employer is investigating options for network redundancy as having a functional internet connection is critical to our operation. We're not in any position to even try applying for PI IPv4 space from APNIC (only using a /28), and are in no way close to being ready to think about going to pure IPv6.
Clients push to us, so we need to have functional DNS as well as link fail-over. We also have multiple public-facing servers offering the same services, so moving to *shudder* NAT or some kind of port proxying isn't an easy option (clients' internal bureaucracies to get firewall ports opened, client configuration, blah blah blah).

So, my question, what are our operational course of action for multi-homing when becoming an AS on the global tubes isn't on the cards?

Cheers


"We're not in any position to even try applying for PI IPv4 space from APNIC (only using a /28)"

Why not?
>From APNIC's website:

Criteria for small multihoming delegations
  • An organization is eligible if it is currently multihomed with provider-based addresses, or demonstrates a plan to multihome within one month.
  • Organizations requesting a delegation under these terms must demonstrate that they are able to use 25% of the requested addresses immediately and 50% within one year.

Very easy criteria to meet.. We had a /27 from our ISP and had no trouble getting a /24 from apnic.
