Routing problems

Plusnet IP 146.200.192.xx

I'm having routing problems to a variety of internet sites.  Other parts of the internet are fine, and I can't see a pattern.  For example:

 

bt.com 193.113.9.164 unreachable

plus.net 212.159.9.2 unreachable

vodafone.co.uk 85.205.252.161 unreachable

virginmedia.com 213.105.9.24 ping 32ms

sky.com 90.216.128.5 unreachable

bbc.co.uk 151.101.0.81 pings 24ms

duckduckgo.com 176.34.155.23 unreachable

google.com 172.217.23.46 pings 25ms

mit.edu 23.66.16.128 pings 34ms

london.gov.uk 104.20.83.234 pings 48ms

theregister.co.uk 104.20.250.41 pings 24ms

johnlewis.co.uk 193.35.250.65 unreachable

rightmove.co.uk 80.64.55.7 unreachable

zoopla.co.uk 176.34.147.219 unreachable

apple.co.uk 17.172.224.108 unreachable

apple.com 17.142.150.59 unreachable

wanadoo.fr 193.252.122.103 ping 49ms

ovh.net 213.186.33.6 unreachable

berlin.de 5.39.246.37 unreachable

madrid.es 195.55.79.118 unreachable

dubai.ae 213.42.85.37 unreachable

comcast.com 69.252.80.75 ping 104ms 

telstra.com.au 203.36.148.11 ping 311ms

 

My guess would be someone messed up their BGP tables?  (Rather interestingly 146.200.0.0/16 is allocated from ARIN rather than RIPE, so it's US IP space)

 

I'm going to try rebooting the router and hope we get an IP in a different netblock, but it'll only pass the problem on to somebody else.

 

Edit: forgot say, it's been like this for a few days

Re: Routing problems

Try changing router dns (assuming it's not a PN one, and thus locked)
to Google's
8.8.8.8
8.8.4.4
Alternatively use these on each device.

Re: Routing problems

He's posted the site name and IP address; the DNS lookup has worked which implies that it is NOT a DNS issue. Your suggestion is therefore irrelevant.

Re: Routing problems

It's a PN router. But anyway, there's no problem in resolving addresses because all of those resolved just fine using the PN nameservers.  The problem is that once you have an IP address half of them can't be pinged.

 

Turning the router off for half an hour got us an IP in a different netblock where the above sites are now routable again.  But that just means somebody else is going to pick up our non-working IP instead.
