Hey Google - Recaptcha sucks
by William Herrin 07 Feb '26

07 Feb '26

I'm at SEATAC airport trying to access www.google.com via the public wifi with Firefox. Apparently you really don't like that because it's stuck in a Recaptcha loop displaying captcha after captcha after captcha. I can't help but notice that Chrome works. It's your _competitor_ Firefox that you don't seem to like. IP address: 198.134.98.50 Time: 2026-02-05T20:03:35Z URL: https://www.google.com/ FIx it, eh? Regards, Bill Herrin

What's up with BGP communities?
by Ronan Pigott 07 Feb '26

07 Feb '26

Hi, First off, apologies if I'm completely lost. I'm not a network professional of any kind, just a random with a question I can't find the answer to on the internet. Basically, I was poking around on this website called bgp.tools and many ASN have a page describing BGP communities known by the network, e.g. https://bgp.tools/communities/13335. It includes descriptions for each one: > 13335:10106 PoP: bos01 > 13335:10358 PoP: cwb03 > 13335:10712 PoP: den04 > 13335:10766 PoP: maa05 > 13335:10920 PoP: zrh02 > [...] I want to know, where does this supplementary information about the communities come from, in this case the "PoP: blah" bits? I don't think it is communicated by BGP directly, so is there some standard out of band mechanism to describe the communities? Or am I just ignorant of this BGP feature? The background is that I live in AZ, USA, and am I subscribed to Cox for my internet service. I noticed that my ping to "example.com" (literally) is slower on IPv6 compared to IPv4: $ ping -4 example.com PING example.com (104.18.27.120) 56(84) bytes of data. 64 bytes from 104.18.27.120: icmp_seq=1 ttl=251 time=9.58 ms 64 bytes from 104.18.27.120: icmp_seq=2 ttl=251 time=5.94 ms 64 bytes from 104.18.27.120: icmp_seq=3 ttl=251 time=7.76 ms 64 bytes from 104.18.27.120: icmp_seq=4 ttl=251 time=6.85 ms [...] $ ping -6 example.com PING example.com (2606:4700::6812:1b78) 56 data bytes 64 bytes from 2606:4700::6812:1b78: icmp_seq=1 ttl=57 time=20.0 ms 64 bytes from 2606:4700::6812:1b78: icmp_seq=2 ttl=57 time=19.0 ms 64 bytes from 2606:4700::6812:1b78: icmp_seq=3 ttl=57 time=20.8 ms 64 bytes from 2606:4700::6812:1b78: icmp_seq=4 ttl=57 time=19.8 ms [...] $ traceroute -IAen4 -z1 example.com traceroute to example.com (104.18.26.120), 30 hops max, 60 byte packets 1 10.3.0.254 [*] 0.249 ms 0.361 ms 0.362 ms 2 10.40.160.1 [*] 8.978 ms 8.658 ms 7.745 ms 3 100.127.73.232 [*] 6.957 ms 8.557 ms 6.881 ms 4 68.1.0.187 [AS22773] 8.067 ms 10.434 ms * 5 184.183.131.9 [AS22773] 13.818 ms 37.728 ms 17.832 ms 6 162.158.140.23 [AS13335] 16.822 ms 8.761 ms 16.768 ms 7 104.18.26.120 [AS13335] 8.813 ms 7.852 ms 9.451 ms $ traceroute -IAen6 -z1 example.com traceroute to example.com (2606:4700::6812:1b78), 30 hops max, 80 byte packets 1 2600:8800:1780:c000::1 [AS22773] 0.315 ms 0.360 ms 0.362 ms 2 2600:8800:17ff:ffff::1111 [AS22773] 6.601 ms 24.911 ms 9.655 ms 3 2001:578:800:6:8100::818 [AS22773] 31.164 ms 8.727 ms 9.075 ms 4 2001:578:900:4::2 [AS22773] 8.763 ms 7.661 ms 6.873 ms 5 2001:578:1:0:172:17:249:32 [AS22773] 29.991 ms 35.838 ms 19.517 ms 6 2001:578:20:a000::7:1 [AS22773] 21.781 ms 20.676 ms * 7 2400:cb00:12:3:: [AS13335] 20.474 ms 20.099 ms 19.824 ms 8 2606:4700::6812:1b78 [AS13335] 20.078 ms 19.747 ms 20.788 ms It's not really a problem, but still I just want to know... why? I thought it would be kind of odd to have example.com hosted only on IPv4 in the Phoenix area so I was trying to see if I could determine whether or not that was the case looking at https://bgp.tools/communities/13335?show-prefixes=13335%3a10066, but I think there just simply isn't enough information available online for me to find out. Thanks, Ronan

AS49666 certain nets out of global table
by Marco Moock 07 Feb '26

07 Feb '26

Hello! Today I noticed various connection attempts from 2001:4188:2::/48 on my TOR relay, but all replies got back a route unreachable. When checking https://bgp.tools/prefix/2001:4188:2:600:10:10:34:36 I noticed that this net was not in the table since start of January. Certain (but not all) of their IPv4 nets are also not propagated anymore to the public bgp looking glasses. Is that part of the Iran internet shutdown or is that a non-political issue? Sadly, their peers don't have RIPE probes with IPv6, so no way to test there. -- kind regards Marco Send unsolicited bulk mail to 1770474123muell(a)stinkedores.dorfdsl.de

DSCP-45 - from Zayo, Hurricane Electric, Lumen
by Livingood, Jason 06 Feb '26

06 Feb '26

In support of IETF L4S and NQB dual queue low latency standards, Comcast (and other networks) have been actively deploying this technology. L4S uses ECN marks and, since ECN is rarely modified in packet headers, this generally works find across domain boundaries. The more challenging one is NQB, since this is predicated on the DSCP-45 mark crossing domain boundaries - and as I think we all know, network domains all implement DSCP differently and so tend to remark DSCP on ingress. Thus, to support NQB, a network will allow DSCP-45 at ingress and classify the traffic as best effort (like default internet traffic). Comcast has done so and we have >10M homes with dual queue (aka Low Latency DOCSIS, a DOCSIS implementation of L4S and NQB). The volume of DSCP-45 traffic is beginning to grow, so we have started to look at traffic sources as we quantify improvements in application quality of experience (e.g., lower loaded latency and lower jitter). Apart from the expected sources we have observed double digit Mbps (far <1% of DSCP-45 volume) - from Zayo, Hurricane Electric, and Lumen. If you run one of those networks, you may want to look at the source of DSCP-45 traffic to ensure your DSCP policies are squared away. Feel free to ping me for more information if you have any questions. Thanks Jason For more info: 1. TSV NQB draft is in the publishing queue (https://datatracker.ietf.org/doc/draft-ietf-tsvwg-nqb/) 2. In support of this, IANA have entered DSCP code point 45 into their registry (https://www.iana.org/assignments/dscp-registry/dscp-registry.xhtml)

Hi, To ensure that the MANRS Actions continue to serve their purpose effectively, MANRS (https://manrs.org) has launched a community survey to gather input on whether a future review of the MANRS Actions is needed — and, if so, what its scope and priorities should be. Your input is crucial, and it only takes 2 minutes to complete. The survey is available here: https://www.surveymonkey.com/r/JG22RHK More details about this particular effort: https://manrs.org/2026/01/help-shape-the-future-of-manrs-actions-community-… More information about the MANRS programs: https://manrs.org/programs/ Thank you for your input Regards, Andrei Robachevsky MANRS Secretariat

Sorry, a short rant about Digital Realty, Hivelocity and 350 E. Cermak

So, it looks like Hivelocity sold their data center at 350 E Cermak to Digital Realty. I guess DR is getting into the business of actually running data centers (Althogh Telx's name is all over the paperwork). We have some servers colocated at this data center. We received no notice of this transfer either by e-mail or on paper. The only notice we got was an invoice. I spent 2 weeks trying to contact them and they never responded to my e-mail until a few days ago. Seems that their outbound MTA is incapable of delivering e-mail to our MTA, which is located AT THEIR DATA CENTER at 350 E Cermak. When I finally got in touch with them after trying for 2 weeks, it appears that 1) They have no online customer management portal (or are not giving us access to it), 2) They don't take credit cards and require a check or wire transfer (so 1960's) and 3) As I said, their MTA seems incapable of communicating with another MTA in THEIR DATA CENTER. Has anyone else had problems with them related to this transfer from Hivelocity? I think Hivelocity sold them their Miami data center as well. Hoping their service gets better soon. My suspicion is that they didn't plan the transition from Hivelocity very well and are scrambling to fix the issues.
