    Status of ipv6 in South Africa

    I've tried this on and off since Afrinic allocated us our first block in 2013. It's a fail. Somewhere you need to perform v6 to v4 conversion. It's not only for websites that haven't enabled IPv6, but also communication with hosted services, such as our ISP management system, SPLYNX, that will...

    Status of ipv6 in South Africa

    Here's the reality. When we enabled v6 by default and basically forced it on our clients, we had more than 60% penetration on our network. That was 10 years ago. The <40% were mostly lazy IT managers who didn't want to roll out the big numbers in their MS Active Directory networks. Today...

    Rural farm near Danielskuil - existing WISP mast, looking to get internet again

    The dish should still be good. You will, however, need an electronics refresh. ie. Replace the Rocket M5 radio with something more up to date.

    Kurlec or HeroTel are the most probable choices.

    Has it been decreased to 100Mb for new signups? That's going to be tight. But still free transit is free transit.

    We use WOL for v6. HE is a big no no.

    Status of ipv6 in South Africa

    I'm going to be brutally honest here. When I rolled out the first FTTH link in South Africa in 2009, there was so much push back that people tried to have me arrested, as they thought I was pulling a fast one. Little did they know I'd just spent five years learning the business in the UK...

    Status of ipv6 in South Africa

    AFRINIC and ZANOG offer no end of free IPv6 training opportunities for ISPs to learn how to implement IPv6. AFRINIC give massive blocks of IPv6 addresses away for free to their members. There is one IP transit supplier in South Africa who provides free IPv6 transit to any ISP that asks. We've...

    Unfortunately, you and I know exactly what sentence entails... Something as simple as advertising certain prefixes to IPT provider A in Jhb and others to IPT provider B in CTN can end in tears. Even if you buy two identical IPT services from two separate transit providers at the same location...

    As you know, I use you at my own home as backup in case we go down. I also have a vodacom LTE in case we're both down. Otherwise sane and totally logical people become irrational when it comes to internet connectivity. They want R20K a month corporate SLAs on R599 a month home connections and...

    CGNAT Woes

    You need to look at one of the smaller ISPs if you want a proper public IP. CGNAT - Carrier Grade NAT is being used my more and more ISPs as IPv4 addresses run out.. https://en.wikipedia.org/wiki/Carrier-grade_NAT Your ISP needs to allocate an IP directly from their access server / NAS. This...

    Best ISP on Octotel, Cape Town

    Our POP in Victoria Centre (diagonally opposite CoCT's POP next to the council offices) has DFA, Openserve and Liquid. In fact, Liquid are in our POP. There's a partition wall between us. We self provision from there. Back in the day (about 10 years ago) CoCT offered a deal where they'd offer...

    Best ISP on Octotel, Cape Town

    This reminds me of that part microwave link through the Northern Cape. One minute Rondebosch to Isando is 18ms and the next it's 160ms. I suspect back in the day when the corporate head hunters went in and reduced the staff compliment from 60,000+ to less than 10,000 many of the people who knew...

    Best ISP on Octotel, Cape Town

    if you're in Rondebosch or Brackenfell, you will be connecting directly to the FNO's infrastructure in their data centres, but if you're in Strand, your traffic will be running over a City of Cape Town layer 2 service that's picked up at CoCT's data centre in Somerset West, then transported back...

    Is there a way to show the various hops' IP addresses or the FQDNs?
