Personally I wouldn't mind more access to dark fiber à la Stokab, much like the dry copper pairs of yesterday. If the default state of muni broadband of is suck, what is the root cause? Is it a people problem and/or can something be done to improve on the default state? Jared

BGP38 egress filter on Ubuntu Server
by Stephen Satchell 02 Jun '21

02 Jun '21

Before I re-invent the wheel, has anyone come up with blackhole route specifications for netplan in Ubuntu servers? Such a capability would perform the egress blocking for an edge server. The table of blackhole routes I would set up: IPv4 Address block Scope Description 0.0.0.0/8 Software Current network (only valid as source address). 10.0.0.0/8 Private network Used for local communications within a private network. 100.64.0.0/10 Private network Shared address space[3] for communications between a service provider and its subscribers when using a carrier-grade NAT. 127.0.0.0/8 Host Used for loopback addresses to the local host. 169.254.0.0/16 Subnet Used for link-local addresses between two hosts on a single link when no IP address is otherwise specified, such as would have normally been retrieved from a DHCP server. 172.16.0.0/12 Private network Used for local communications within a private network. 192.0.0.0/24 Private network IETF Protocol Assignments. 192.0.2.0/24 Documentation Assigned as TEST-NET-1, documentation and examples. 192.88.99.0/24 Internet Reserved.

Does not need to be – just a suggestion based on the thinking that these locales may have more dense populations and thus perhaps higher FTTH penetration for a longer period of time. But the data from any network will certainly have some interest.

The last 5 yrs. have definitely changed the profile of a typical home user. A 4M upload pipe, will hit bottlenecks with all the collaboration that is happening remotely. I'm not sure ratio is the right thing to focus upon - especially as asymmetry has grown the last few years due to the rising using of streaming video services and greater availability of 4K-resolution content. Ratio seems like more a reflection of current applications and usage patterns. (It would be fascinating to see a non-US FTTH provider that was 1G/1G or greater share their actual usage ratio.) JL

QUIC, Connection IDs and NAT
by Robert Brockway 01 Jun '21

01 Jun '21

QUIC has Connection IDs independent from IP. This was done to make it easier to move from one IP network to another while keeping connections active, as most here will know. Does the existence of Connection IDs separate from IP mean that the host/IP contention ratio in CGNAT can be higher? IE, can a single CGNAT device provide Internet access for a greater number of end-users? And if so, does this reduce demand on IPv4 resources? It's ok, I'm wearing a fire-resistant suit with self-contained breathing apparatus as I type this. Rob
