Geolocate data for allocated blocks

I am seeking assistance in getting nets I’ve allocated (several months ago) to an office in another RIR region to properly update its geolocate data. In this particular case, I have a net in use in India, but currently reflects Houston as its address although the allocation indicates otherwise

Re: Geolocate data for allocated blocks

Most places are using Maxmind for their GeoIP. You can ask them to update the database here: https://support.maxmind.com/geoip-data-correction-request/ It takes about a month in my experience to see results. Make sure the data in whois is also up to date for your blocks. On Tue, Dec 19, 2017 at 4

Multi lane optics

Hello, Some optics are implemented with multiple lasers such as QSFP+ with 4x 10G = 40G or QSFP28 with 4x 25G = 100G. How is the ethernet traffic load balanced between those lanes? Is it bit by bit or more like LACP (packet by packet)? I need to make sure my solution will handle 10G streams

Re: Companies using public IP space owned by others for internal routing

While a single network gets at /64, isn't the practice suppose to be providers allocating a /56 or a /60 for home users (you know so your IOT, wired lan, wifi, guest network, gaming systems, bathroom, bedroom, etc. can all be on their own networks)? ---

Re: Companies using public IP space owned by others for internal routing

If we allocate a /64 like we do single ipv4 addresses now the space gets 2^56 (16777216) times larger; but if we start doing something crazy like allocating a /48 or /56 that number plummets. (256 times larger, and 65536 times larger respectfully.) But then again I'm bad with math, maybe not?

contact for WCGDB routing registry?

Does anyone have a contact for the WCGDB RR? They've got an invalid object registered that is being mirrored to other providers, but I am unable to find any working poc. Also why is wcg.com running an RR that's being mirrored by t1s to begin with? (changed had wcg.com email addr.) cheers -chris
