Buying IPs with poor reputation
by Ross Tajvar 19 May '21

19 May '21

I'm curious if anyone has experience deliberately buying blacklisted blocks, or blocks that otherwise have poor reputation. Is there a significant price difference? How do you seek them out? Most of the sellers I've found seem to focus on blocks with good reputation, or on improving the reputation of a bad block. But I am interested in purchasing some IPs for internal services where reputation doesn't really matter. Thanks, Ross

NAT/CGNAT IP address/users ratios
by Scott, Thomas 18 May '21

18 May '21

Hello NANOG (and friends), Asking if anyone would care to share their CGNAT and NAT ratios. We're looking at some best practices and I wanted to see what the community at large has seen working, and not working. I am by no means a NAT expert, and usually I see the other end where it's clearly *not* working. Does anyone have estimating formulas for devices/users to internal blocks to public IPs?

Georgia DOL Contact
by Joe Freeman 17 May '21

17 May '21

Is anyone on the list with Georgia Department of Labor? I've got customers having problems logging into their website and need a good contact there to troubleshoot. Routing appears ok as we can get to hosts on that subnet, so I suspect the issue is above layer 3. Thanks- Joe

RE: Juniper hardware recommendation
by Michael Fiumano 17 May '21

17 May '21

If accurate interface stats are important to you, MX’s don’t support accurate SNMP Interface Utilization, ie they don’t comply with RFC2665/3635, which seems like a fairly basic thing to do but they decided not to, and has been impactful to me in the past. So, any SNMP monitoring of an interface will always show less utilization than what is actually occurring, possibly leading to a false sense of security, or delay in augmentation. Would also affect usage based billing, if you do that. https://www.juniper.net/documentation/us/en/software/junos/network-mgmt/top… For M Series, T Series, and MX Series, the SNMP counters do not count the Ethernet header and frame check sequence (FCS). Therefore, the Ethernet header bytes and the FCS bytes are not included in the following four tables: ifInOctets ifOutOctets ifHCInOctets ifHCOutOctets Thanks, Michael Fiumano *From:* NANOG *On Behalf Of *Mark Tinka *Sent:* Monday, May 10, 2021 10:25 AM *To:* nanog(a)nanog.org *Subject:* Re: Juniper hardware recommendation On 5/10/21 16:19, aaron1(a)gvtc.com wrote: I prefer MX204 over the ACX5048. The ACX5048 can’t add L3 interface to an mpls layer 2 type of service. There are other limitations to the ACX5048 that cause me to want to possibly replace them with MX204’s. But in defense of the ACX5048, we have gotten some good mileage (a few years now) of good resi/busi bb over vrf’s and also carrier ethernet for businesses and lots of cell backhaul… so they are good for that. I’ve heard the ACX5448 was even better. Trio will always provide better features, but come with the price tag to boot. I’m looking at the MX240 for the SCB3E MPC10E hefty with 100 gig ports You might want to look at the MX10003, in that case, as well. We are deploying those for 100Gbps service (customer-facing). Works out cheaper than offering 100Gbps service on the MX240/480/960 for the same task. Mark.

Hello NANOG'ers! I'm observing a near global outage of DNS services from d.nic.so. This appears to be an AfriNIC anycast DNS service. Does anyone have contacts at AfriNIC for their DNS systems available? e.nic.so seems to be responding (hosted behind PCH, thanks Woody!). Tom -- Tom Daly tjd(a)q7.io

Anyone from REACH IRR on this list?

Dear REACH admins, >From the email address in Merit’s IRR Directory [Reference: http://www.irr.net/docs/list.html#REACH ], I contacted you at dbadmin(a)telstraglobal.net regarding taking-down a fake IRR entry of my prefix [original email attached below], but got the response from Gmail saying that it cannot contact your email server. Please kindly consider my request.

We have already registered all of our prefixes with the APNIC RPKI Trust Anchor. We present the following URL as an authentication of prefixes ‘ownership’. [Reference: https://rpki.cloudflare.com/?view=explorer&validateRoute=9411_&asn=9411&ext… ] However, your database is currently announcing 1 fake entry incorrectly listing AS4750 as the origin of *our* 158.108.0.0/16 netblock. [Reference: https://bgp.he.net/net/158.108.0.0/16#_irr] That fake entry represents a security threat to our network.

Juniper hardware recommendation
by Javier Gutierrez Guerra 14 May '21

14 May '21

Hi, Just out of curiosity, what would you recommend using for a core router/switch from Juniper? MX208,480,10K Datasheets show them all as very nice and powerful devices (although they do use a lot of rack space and side to side airflow is painful) but I’m just wondering here what most people use and how good or bad of an experience you have with it 😊 Thanks, Javier Gutierrez Guerra Network Analyst CCNA R&S, JNCIA Westman Communications Group Phone: 204-717-2827 Email: guerraj(a)westmancom.com<mailto:guerraj@westmancom.com> [WCG_Corp_Logo_horiz_cFullcolorHR]<http://westmancom.com/personal/> [cisco-certified-network-associate-routing-and-switching-ccna-routing-and-switching]
