Help with removing DNS shinkhole FP from Charter/Spectrum
by Validin Axon 23 Apr '24

23 Apr '24

Looking for some help/advice. Spectrum is sinkholing my company's domain, validin[.]com, to 127.0.0.54. The sinkhole responses come from their recursive DNS servers, 209.18.47.61 and 209.18.47.62, which are defaults for and in use by many of their customers and are only reachable from within the Spectrum network. I've had 4 people over the last week (think: customers, prospects, etc) who use Charter/Spectrum tell me that they have difficulty accessing my website as a result of this sinkhole behavior. This behavior is causing reputational harm to my company. I've personally confirmed this behavior from the Spectrum network (I am also a customer) using dig to test their DNS servers: ``` $ dig +short @209.18.47.61 validin.com 127.0.0.54 $ dig +short @209.18.47.62 validin.com 127.0.0.54 ``` Using Cloudflare/Google/etc works correctly: ``` $ dig +short @1.1.1.1 validin.com 137.184.54.107 157.245.112.183 $ dig +short @8.8.8.8 validin.com 157.245.112.183 137.184.54.107 ``` I suspect my domain was blocklisted last year when a threat researcher included my domain name in a blog post about a threat they were investigating and cited my company as the source for their data. Someone scraped that post, and my company's domain was accidentally added to two Alient Vault OTX pulses and at least one collection on Virus Total. I removed the domain via false positive reporting from everything I could. However, it appears that being added to Spectrum's DNS sinkhole list is effectively permanent and there's no clear path for false positive remediation. I've tried the official Spectrum support lines for months to no avail, and recently tried reaching out on Twitter, but have had no success there either. I'm clearly not able to find the right people through these routes, as none of the people I reach understand the difference between a DNS sinkhole and an IP block list and don't appear to be aware that DNS blocklisting is a separate behavior from their opt-in content filtering via Security Shield. So, if someone could please help me find the team or individual responsible for Spectrum's DNS sinkhole behavior, I would be exceptionally grateful. :-) As I mentioned, this is causing reputation harm, so switching my own DNS servers is not sufficient. People who need to reach me, can't. So, I would appreciate any other help or advice you have, Kenneth

Question about mutual transit and complex BGP peering
by Sriram, Kotikalapudi (Fed) 22 Apr '24

22 Apr '24

Requesting responses to the following questions. Would be helpful in some IETF work in progress. Q1: Consider an AS peering relationship that is complex (or hybrid) meaning, for example, provider-to-customer (P2C) for one set of prefixes and lateral peers (i.e., transit-free peer-to-peer (P2P)) for another set of prefixes. Are these diverse relationships usually segregated, i.e., P2C on one BGP session and P2P on another? How often they might co-exist within one single BGP session? Q2: Consider an AS peering relationship that is mutual transit (i.e., P2C relationship in each direction for all prefixes). Is this supported within one single BGP session? How often the ASes might setup two separate BGP sessions between them -- one for P2C in one direction (AS A to AS B) and the other for P2C in the opposite direction (AS B to AS A)? Thank you. Sriram Kotikalapudi Sriram, US NIST

Re: Help with removing DNS shinkhole FP from Charter/Spectrum
by Validin Axon 22 Apr '24

22 Apr '24

Hi Mel, I appreciate the suggestion. During my earlier research, I'd noticed that as well. However, the DNS block includes all validin.com subdomains, covering those on completely different ASNs. It also does NOT affect other domains that resolve to the exact same IP addresses (e.g., validin.net) So, I'm inclined to think it's not that simple, unfortunately. I'd considered switching domains, but that doesn't guarantee the problem wouldn't just reappear again, and it'd impact the search engine ranking we've built up. We rely 100% on inbound, so that'd be a big set back.

I notice from MXToolbox.com that your domain’s IP address is on the UCEPROTECTL3 blacklist. This is a notoriously evil blacklist that charges people for removal. This may be why Spectrum is blackholing your domain. Most respectable ISPs won’t use it. But Spectrum… There is no delisting procedure without making a “donation” to the UCEPROTECT3 black sparrow account. They’re famous for blacklisting large swaths of IP addresses that catch up innocent parties that have never spammed a flea. -mel On Apr 22, 2024, at 4:51 AM, Validin Axon <axon(a)validin.com> wrote: Looking for some help/advice. Spectrum is sinkholing my company's domain, validin[.]com, to 127.0.0.54. The sinkhole responses come from their recursive DNS servers, 209.18.47.61 and 209.18.47.62, which are defaults for and in use by many of their customers and are only reachable from within the Spectrum network. I've had 4 people over the last week (think: customers, prospects, etc) who use Charter/Spectrum tell me that they have difficulty accessing my website as a result of this sinkhole behavior. This behavior is causing reputational harm to my company. I've personally confirmed this behavior from the Spectrum network (I am also a customer) using dig to test their DNS servers: ``` $ dig +short @209.18.47.61 validin.com<http://validin.com> 127.0.0.54 $ dig +short @209.18.47.62 validin.com<http://validin.com> 127.0.0.54 ``` Using Cloudflare/Google/etc works correctly: ``` $ dig +short @1.1.1.1<http://1.1.1.1> validin.com<http://validin.com> 137.184.54.107 157.245.112.183 $ dig +short @8.8.8.8<http://8.8.8.8> validin.com<http://validin.com> 157.245.112.183 137.184.54.107 ``` I suspect my domain was blocklisted last year when a threat researcher included my domain name in a blog post about a threat they were investigating and cited my company as the source for their data. Someone scraped that post, and my company's domain was accidentally added to two Alient Vault OTX pulses and at least one collection on Virus Total. I removed the domain via false positive reporting from everything I could. However, it appears that being added to Spectrum's DNS sinkhole list is effectively permanent and there's no clear path for false positive remediation. I've tried the official Spectrum support lines for months to no avail, and recently tried reaching out on Twitter, but have had no success there either. I'm clearly not able to find the right people through these routes, as none of the people I reach understand the difference between a DNS sinkhole and an IP block list and don't appear to be aware that DNS blocklisting is a separate behavior from their opt-in content filtering via Security Shield. So, if someone could please help me find the team or individual responsible for Spectrum's DNS sinkhole behavior, I would be exceptionally grateful. :-) As I mentioned, this is causing reputation harm, so switching my own DNS servers is not sufficient. People who need to reach me, can't. So, I would appreciate any other help or advice you have, Kenneth

When I worked in Malaysia back in the day (2007 - 2012), WAN-PHY was generally asked for for 10G services, until about 2010; when folk started to choose LAN-PHY. The reason, back then, was to get that extra 1% of pipe bandwidth :-). Oh I don't think OTN or WAN-PHY have any large deployment future, the cheapest option is 'good enough' and whatever value you could extract from OTN or WAN-PHY, will be difficult to capitalise, people usually don't even capitalise the capabilities they already pay for in the cheaper technologies. Of course WAN-PHY is dead post 10GE, a big reason for it to exist was very old optical systems which simply could not regenerate ethernet framing, not any features or functional benefits. -- ++ytti

constant FEC errors juniper mpc10e 400g

We recently added MPC10E-15C-MRATE cards to our MX960's to upgrade our core to 400g. During initial testing of the 400g interface (400GBASE-FR4), I see constant FEC errors. FEC is new to me. Anyone know why this is occurring? Shown below, is an interface with no traffic, but seeing constant FEC errors.
