Their provider has peering issues, or simply got turned off and their
provider isn't null-routing their smaller block.

Probably your gateway/router. 192.168.0.1 is default.

Weird your provider is filtering icmp, or you are. Maybe they do is
they don't want someone topology mapping satellites per the government.
Five hops to get to their internet provider for bgp handoff from your
uplink gateway.

Your provider peers with Level 3 from denver land gateway, to san jose,
paying them for internet transit. They respond outside the satellite
network to the traceroute as a provider should. They pass you off to
the next bgp autonomous system in path.

L3 hands off from san jose to chicago, and launches to netherlands
within this eurorings.net next in the as-path.

Probably a mutual peering switch at the euro data center.

https://www.ultratools.com/tools/asnInfoResult?domainName=3265> is
still advertising the route, but there's a loop in routing (conflicting
routes) internally where they hand off to a customer (old customer?):
show ip bgp <http://xostats.xo.com/cgi-bin/xostats/diagtool-pub/bgp>
82.94.226.104
BGP routing table entry for 82.92.0.0/14, version 123161444
* * * Advertised to update-groups:
59
* * * Refresh Epoch 1
* * * 2828 6939 3265
<https://www.ultratools.com/tools/asnInfoResult?domainName=3265>,
(received & used)
... so they take your request within the /14 aggregate that route that
falls in, but no one home at that more specific route/ip address, and
the trace bounce until ttl's expire @ 30 as a precaution against bad
network administration like that (this is what sinkhole routing to null0
is for).
FWIW, I get the same from cox here to that IP, but that IP isn't what
blender.net resolves to:
mb@host:~$ ping blender.net

What is this ip? Do you have cached indefinite dns or something for it
as blender.net? What does it resolve to for you?
-mb
