AS112 and BIRD
AS112 provides an anycasted reverse DNS sink hole for the private addresses set aside in RFC1918 and RFC6890. Using BIRD to inject an AS112 instance into your own system is quick, easy, and painless!AS112 and Exabgp
AS112 provides an anycasted reverse DNS sink hole for the private addresses set aside in RFC1918 and RFC6890. Using exabgp to inject an AS112 instance into your own system is quick, easy, and painless!HA Recursive DNS with dnsdist and exabgp
I've wanted to use exabgp along with dnsdist to provide anycasted, highly available recursive DNS servers ever since discovering dnsdist.MikroTik, VRRP, and IPv6
I recently setup IPv6 first-hop redundancy in my colocated environment using MikroTik and VRRP. It didn't work the same way I'd come to expect from using it in IPv4 environments and I set out to figure out why.Nagios and IPv6
While I've had most of my services IPv6 enabled for quite a while, I have not set up monitoring of those services over IPv6 yet. This blog post is a summary of my experiences IPv6 enabling my nagios setup.Using ULA and NAT66
What are IPv6 Unique Local Addresses (ULA)? Why would you ever want to use NAT with IPv6? These two questions are directly related. If you were running services with ULAs, you would want to translate those addresses into public addresses. This is where NAT66 comes in.Troubleshooting ICMPv6 with tcpdump
I've previously written about my OpenBSD PF firewall in front of my VM server at my colo. I had a firewall rule which used the following variable: icmp6_types="{ 2, 128 }". This wasn't working properly on the LAN side, and I had to disable the ICMPv6 restrictions to get things back to working. I wanted to fix this permanently, the right way, by determining what needed to be allowed and what could be denied without breaking things.Fully IPv6 Enabled
