Just to note there are two products, OSA Filter Connect, which uses Adva
equipment and is documented in SIN 489, then OSEA Filter Connect, which uses

Assuming you mean OSA Filter Connect, then it’s documented in SIN489 —
obviously it depends on the filter module and single/dual fibre.

Assuming it is the same as the linecards, IR would be limited to 32 L3VPNs.

Hi,
Sorry to bring up the B word but is Brexit causing UK operators to
have to renegotiate transit and peering arrangements with their
continental counterparts?
Transit and peering not so much as we do most of it in the UK so getting
the packet passports is their problem. :-)
We’ve been
ISP B is just starting out and has to pay RIPE fees and get on a waiting list
for a /24. All the while being unable to provide IPv4 services.
Or go to a broker and buy a /24 or whatever from a network that can
make do with fewer addresses.
The good news at the moment is that the RIPE

Most Universities have addresses directly allocated to them from days

With all online events, ‘non-chaotic’ means (IMHO) moderated by
someone other than the speaker (come to think of it, that applies to
in-person events just as much).

Over the last year I've sent multiple abuse reports to

That surprises me. There are definitely CSIRT folk

Is this not possible within the native whois client?
One reason it’s difficult is that there isn’t a 1:1 mapping between
ASN and AS-SET.
For example, AS786 uses AS-JANETUS, AS-JANETPLUS, and AS-JANETEURO (the
names are largely historic, JANETUS is for transit, JANETEURO is for the

Hmm, I've asked the folk here to check where the typo crept in and do the

Good venue, good people, good content, good hosting, tasty shortbread biscuits
and delicious scones (not had scones in a break since Bristol?). Thanks to all
involved.

I have tried this on a number of occasions and not been successful but it
doesn't hurt to try again I suppose! Even a small sporting event with rings
and billions of viewers didn't swing it!

To heavily paraphrase Dame Edna, “So, HMRC, why didn’t you want to let the
multi-billion-pound sporting event off a little import duty?” :)
Bah. Mrs Merton, not Dame Edna, natch.
So not that much considering cost of CGN which actually works.
Even more silly is the fact space is still available from ARIN on normal
terms (they're not into their last /8 yet) so it's clearly some form of spam.
Note they're also asking for IPv6 space...

Most people will still filter on a /24 I believe , although some will filter
on a /22 (Minimum RIPE Allocation)
I'll also just plug a talk at tomorrow's meeting by Olaf Maennel of
Loughborough University -- Observing Limited Visibility Prefixes in the Wild.
More details on the agenda:
Then, have the ISP do some magic* to make IPv4 visible.
* I'll leave it as an exercise to those more sober and less tired to
solve that problem. But I guess it'd mean some clever DNS
capture/re-map for all locations which don't have addresses,
remap them to a local 6 to 4 proxy.

Hi,
Some of you may be interested in this.
