Need Zayo to fix a PTR Giorgio Bonfiglio via NANOG (May 10)
Soneone in Zayo forgot a little “.” after “zayo.com <http://zayo.com/>” in a DNS zone and this is a/ messing up the
formatting of a very legacy mtr report I run and b/ messing up with my OCD:

Re: Geolocation and OfficeDepot.com Abdullah DevRel of IPinfo via NANOG (May 09)
Hi Cory,

I work for IPinfo. We monitor NANOG threads regularly. Can you share the ranges or ASN with me? IPinfo is reporting the
correct location, but I can check our internal data for any hints or overrides worth investigating. It is possible
Office Depot's geolocation provider is prioritizing some location hints over published geofeeds.

Office Depot is not a customer of ours, and I do not have a direct contact there, but I will see...

Re: "Peering Router" Seth Mattinen via NANOG (May 08)
I personally don't mix transit and peering duties on the same device. I
have a dedicated router for peering sessions and a dedicated router for
each transit provider. I find it easier to manage and it limits scope if
one of them has a problem or needs an update since it only affects its
own playground.

Re: Does SOA expire for root matters? Brandon Martin via NANOG (May 08)
Unless the server stores a negative/expiry result for the domain, which
I don't think any major implementations do, it should just fall back to
its hints file which would allow it to bootstrap itself again the same
as upon initial startup.

In that respect, I don't think the SOA expiry is a big deal. You want
it to be long enough that normally-running systems won't constantly keep
having to resolve it or fall back to their...

Does SOA expire for root matters? Anurag Bhatia via NANOG (May 08)
Hello everyone

Was wondering if anyone who has worked across root servers ops could answer
about the expire value in SOA record:

dig @a.root-servers.net. . soa +short
a.root-servers.net. nstld.verisign-grs.com. 2026050800 1800 900 604800 86400

So 604800 (1 week) would actually make the DNS replicas to stop resolving
if disconnected for an extended period of over a week from their master?
Unsure of tech root operators use to replicate zone (if...

Spoofer Report for NANOG for Apr 2026 CAIDA Spoofer Project via NANOG (May 08)
In response to feedback from operational security communities,
CAIDA's source address validation measurement project
(https://spoofer.caida.org) is automatically generating monthly
reports of ASes originating prefixes in BGP for systems from which
we received packets with a spoofed source address.
We are publishing these reports to network and security operations
lists in order to ensure this information reaches operational
contacts in these...

Re: Geolocation and OfficeDepot.com Harald Koch via NANOG (May 07)
I can access officedepot.com from multiple Canadian IP addresses (Bell Canada, University Health Network). Checking, my
IP addresses _are_ located in Ontario, Canada. I wonder if you have a different problem?

Re: Geolocation and OfficeDepot.com Tim Burke via NANOG (May 07)
iirc, most of the major retailers use Akamai. Check against https://whatismyip.akamai.com/advanced to see what their
records show.

Unfortunately, I’m not sure how to correct that data if it is indeed incorrect… but I have seen many cases where
Akamai’s data is incorrect… even moreso than the ipinfo folks that think traceroute is a valid way to geolocate.

Greetings,

Re: Geolocation and OfficeDepot.com SynSeer via NANOG (May 06)
Unfortunately, every single one of the sites returns the correct results,
so I still have no idea where Ontario, Canada is being reported. Still,
this is a great site for lookups, and I've bookmarked it.

Thanks!

Re: Geolocation and OfficeDepot.com Calvin Judy via NANOG (May 06)
This sounds like they could be using a downloaded/flatfile database from one of the common GeoIP providers, and simply
haven't updated it in a while.

RE: Geolocation and OfficeDepot.com dcppollselect--- via NANOG (May 06)
https://www.iplocation.net/ip-lookup will check 9 different geolocation
providers.

Geolocation and OfficeDepot.com SynSeer via NANOG (May 06)
Greetings,

We've been struggling with incorrect geolocation for an IPv4 network we've
been leasing for about five months. Our customers can't access
officedepot.com because some database thinks the IP address is in Ontario,
Canada. We have a public geofeed published and ARIN comment on the prefix
to utilize the feed. We just can't seem to figure out where the remaining
references to Canada are coming from. We've...

This is the internet my man. You don’t ask people how to do things;
you just tell them what you’re going to do, and people will bend over
backwards to show you how wrong you are and how this and that would be
better.
With luck, you can make a PhD thesis out of it. Honestly, many of the
