Out of curiosity, who were the previous owner(s), it seems that ARIN 
only shows the current owner with any history? If it was a 
Chinese/Russian block, you might be out of luck.

Re: Multi-CDN Strategies

[Chris Woodfield]

I have some experience with this; a few things off the top of my head:

- It’s usually best to leverage some sort of “smart” DNS  to handle CNAME 
distribution, giving you the ability to weight your CNAME distribution vs. only 
using one CDN all the time, or prefer different CDNs in various global regions. 
I’ve had decent experience with Dyn here, but Route53 has all the features 
you’d want as well. If possible, write tooling towards your DNS provider’s API 
to automate your failovers.

- Weight your distribution such that you never have one CDN turned off 
completely; you’ll want a small trickle of user traffic hitting every CDN so 
that the caches won’t be cold when you switch over to it.

- Make sure you have a distributed metrics service (ThousandEyes, WebMetrics, 
et al) testing your CDNs individually as well as the external hostname.

- Stay away from HTML- or Header-munging features when possible; stick with 
feature sets that are common (and implementable in similar ways) across your 
providers. (Similar advice goes for multi-vendor *anything*, TBH)

I could keep going, but if so, I might as well stick them into a powerpoint and 
submit a talk for Bellevue :)

Purchased IPv4 Woes

[Pete Baldwin]

Hi All,

Hopefully this is not taken in bad taste.   Our organization 
purchased some IP space last year (163.182.192.0/18 to be specific), and 
it appears that this block must have been used for less-than-admirable 
purposes in the past.


We have been trying to clean up the reputation where possible, and we do 
not appear to be on any blacklists, but we do appear to be blocked from 
a lot of networks across the US/Canada.I am noticing a lot of name 
servers blocking our requests, many web servers, gaming servers, mail etc.


This is a transition block for us to move towards v6 everywhere, but we 
have many systems that will need to rely on this block of space for some 
time to come.


We are a small rural co-op ISP in Ontario, and I am just writing this 
email as an extra plea so that if you happen to run a network that has 
this entire range on your naughty list, we would appreciate you giving 
it another chance.  I can be contacted on or off list, thanks.

critical mass update on IPv6

[Ca By]

Just update for those that care.

As you may know, all the major cellular providers in the USA (VZ, AT,
T-Mobile, Sprint) support IPv6 by default on many models of phones.
Comcast and AT and other large broadband players also have IPv6 widely
deployed by default

http://www.worldipv6launch.org/measurements/

Most of the major (elephants) content is IPv6 (Google, FB, Netflix, ...)

And now the other end in the cloud is coming along nicely

https://aws.amazon.com/blogs/aws/aws-ipv6-update-global-support-spanning-15-regions-multiple-aws-services/

https://docs.microsoft.com/en-us/azure/load-balancer/load-balancer-ipv6-overview

https://cloud.google.com/compute/docs/load-balancing/ipv6

Not to mention that Digital Ocean , Softlayer / IBM, Linode, and others
also support IPv6

And now you are seeing ipv4 lose support in various classes of products
like set-top boxes (
http://corporate.comcast.com/comcast-voices/world-ipv6-launch-four-years-later-taking-stock-and-looking-forward
) and static IPs (

)
