Computers connected using the protocols specified in BBN Report 1822 (https://walden-family.com/impcode/BBN1822_Jan1976.pdf) NCP was alternately referred to as the Network Control PROGRAM and the Network Control Protocol. It essentially played the role of TCP, managing pairs of simplex connections. Routing was completely dynamic - that was the whole point of the IMP software. And routing did NOT require email addresses - those operated much further up the protocol stack. Perhaps you're confusing this with UUCP mail addressing ("bang" paths).

ARIN POC RegDate...
by bzs＠theworld.com 25 Oct '21

25 Oct '21

Perhaps silly but am I the only one with an ARIN POC RegDate of 1970-01-01? I've been in that db a long time but not quite that long. Does it matter? I have no idea what the correct date might be so the instructions to correct don't help. If I needed that info I'd consult the ARIN DB but I guess not. I guess I'm wondering if it's just their temporary DB glitch so I should ignore it. The rest of the info is perfect beyond my wildest dreams. -- -Barry Shein Software Tool & Die | bzs(a)TheWorld.com | http://www.TheWorld.com Purveyors to the Trade | Voice: +1 617-STD-WRLD | 800-THE-WRLD The World: Since 1989 | A Public Information Utility | *oo*

Smokeping - EchoPingHttps
by Mike Hammett 24 Oct '21

24 Oct '21

I used EchoPingHttps for the first time today. I pulled up the top 20 sites (well, removing duplicate sites from the same company) from Alexa and put them in to trend response times. I've had "this feels slow" over the years, but no way to really track that other than feels and pings. I noticed that a few (Facebook, Salesforce, ESPN, and Zillow) don't chart at all, with varying errors in a smokeping --debug. I've noticed that a couple more (Amazon and Etsy) are fickle in their responses. I assume if they're not responding, they're poo pooing on my fake client. Am I in the right ballpark? Next, is there a better way of doing this? I saw the curl plugin, but it was only after I had seen EchoPingHttps, so maybe curl is "better." ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com

I rebuilt it into AC, considering the ISP also owned the data centre (most of whose customers bought AC). The space we freed up and the ease of deployment was night & day. Currently, we obviously need DC for the terrestrial Transport and wet plants (because that's just how classic telco rolls), but I also switched all IP/MPLS gear to AC soon as I arrived. Heck, even the Arbor (now Netscout) gear, as well as the HP server rack, was loaded with DC power supplies. Those things just had to go. There is an avenue of pleasure in not having to spend inordinate amounts of time adding major electrical planning to deploying/decommissioning a router, switch or server. But yeah, I know the AC vs. DC discussion can become a rat hole. I'm aware of data centre operators now providing DC as an option for their expansion projects, when they previously had it as the norm, FWIW. Mark.

Re: [routing-wg] Relative size of IRR registries
by Rubens Kuhl 23 Oct '21

23 Oct '21

You are right on all counts but (3). IRRd 4.2 has a feature called scope filter, and the results below had the following in effect: scopefilter: prefixes: - 10.0.0.0/8 - 172.16.0.0/12 - 192.168.0.0/16 asns: - 23456 - 64496-64511 So they already excluded those easy to detect unassigned blocks. It doesn't exclude blocks that are assigned by IANA but not yet by a RIR/NIR (like Team Cymru bogon feeds), but is good enough.

Relative size of IRR registries

Network visibility
by Nat Fogarty 22 Oct '21

22 Oct '21

Hi there, I'm interested in what you good folks do in terms of network visibility. My interests are around Service Provider space - visibility for IPoE, PPPoE, TCP(User Experience). I use a product called "VoIPmonitor" for all things VoIP - and it is one of my favourite tools. It is a web gui for sip/rtp/etc. Is there a similar tool in the Ethernet(L2)/IP(L3) space? Are operators using tcpdump/wireshark for this - or is there a voipmonitor-esque tool out there? Cheers, Nathaniel
