We're looking at building into a DC in Europe this year and I wanted to run a few questions by the community and make sure I'm not too far off course.
We currently have v4 space from ARIN and operate a multihomed datacenter in the US. This thread from September 2012, though the reverse of my situation, makes it seem like I should be able to work with ARIN to satisfy all of our v4 and v6 needs regardless of where in the world I plan to advertise the space. Obviously this would be really convenient for us since we already have a relationship with ARIN. http://mailman.nanog.org/pipermail/nanog/2012-September/052137.html
So my questions are: * Is it ok/recommended to advertise v4 ARIN space (say a /23) to my upstream ISPs in Europe?
Yes, expect there to possibly be geolocation issues.
* Is it ok/recommended to advertise v6 ARIN space to my upstream ISPs in Europe? (I suspect we'll get a /44 block to carve up since we fit in the "more than one but less than 12 sites" category)
I would recommend looking at RIPE membership depending on the nature of your business. It may make sense to do this.
* Should I use a single AS for both North America and European data centers? It will be the same small team managing them today but it's not like the sites are linked together to form any kind of transit network.
I see no issues with a single-AS. What you want to look at is if it makes sense. If you have just one link connecting your EU-North America sites, it may make sense to use a different ASN in the event of that circuit going down. If you use diverse cable systems, you are likely "OK". Make sure you track what system you are on, when there is an outage, it can take weeks to recover.
Also, is there a European version of RADB with which I should plan to register my prefixes?
This would be the RIPE database, but most of the routing registries mirror each other, so you likely are fine using just one. (the daily sync issues aren't there anymore, it's realtime in every case i've observed in modern history). - Jared
