Multihomed Central Office - Public Address Space
Posted on 2013-06-20
I have been given the responsibility of somehow multihoming my central office location to the Internet. I have two separate Internet providers who claim to offer the bandwidth that I need for each link. My question is regarding public IP address space. Currently, we purchase our IPs through our single provider. These are, of course, PA addresses. To my knowledge, these would not suffice in a dual-homed environment with two ISPs. I did some quick research on ARIN's website and it looks like we are too small to be candidates for a direct end-user assignment - I'm only using half of a /25 currently. ARIN's policy requires you to use at least 25% of a /24 upon purchase and 50% within a year.
So, does anyone out there know what would be the best course of action for my enterprise? I am a higher education institution in Texas. I'm a member of Educause, but I'm not sure they can sell me what I need in this case. Once I get the address question answered, I would then need to know what the best method to purchase a BGP ASN would be.
