LRs, but ZR and DWDM are still a ways out. There are also some CWDM
units in the works, but because SFP+ doesn't support onboard EDC you
are limited by dispersion to 10km in the traditional 8ch 1470-1610nm
CWDM space over SMF28.

The IEEE expects the MAC-48 space to be exhausted no sooner than the
year 2100[3]; EUI-64s are not expected to run out in the foreseeable
futur

FYI this guy has been spamming individuals and PeeringDB contacts for a

lly as you try to move to 10G speeds and beyond, is IMHO
not worth the relatively small short term cost optimization.

That might explain why they're only announcing it behind Cogent. :)

27;re left with. So far all we've really
done with v6 is created a flashback to the days when every end user
could get a /24 just by asking, every enterprise could get a /16 just by
asking, and every big network could get a /8 just by asking, just bit
shifted a little bit. That's all well a
black market of buying and selling people's active IPv6
addresses from various website logs and the like, so hax0rs will have
something to scan. In a few years time it will probably be popular with
end users to periodicially "rotate the shield frequencies" with their
final 64 bits, o
space (and a lot of prefix bloat for when we start using more
than 2000::/3), which is a FAR cry from the 2^128 "omg big number, we
can give every molecule an IPv6 address" math of the popular
imagination. :)

provide. :)

to handle it fine, though admittedly it breaks my automatic mental
calculations of "what is the peer IP" something fierce.

cycle then track your interfaces by their names, pretty much
every modern poller system can manage this. MRTG is absurdly old, slow,
and generally nasty, and should not be used by anyone in this day and
age.

t :P). Remember that 1550nm is
infrared and very effectively filtered by the human eye, so even a
+17dBm output EDFA (the max output for most metro systems) is still
going to be class 1M and effectively safe as long as you don't stare at
it in a microscope.

so depending on the fiber conditions
and number of splices/panels along the way you could potentially expect
to get the entire distance out of a "standard" 100km optic.

million packets/sec of UDP/53 DoS traffic, starting at about the same
time as the UltraDNS problems. No clue if it's related, but it certainly
sounds suspicious. :)

massive
change in the economics for the IP network operators will obviously
result in major changes to the amount of traffic delivered over IX
fabrics vs private interconnection. Again, something you could have
actually asked operators about rather than making up conclusons in your
head.
