Ipv6
MikroTik, VRRP, and IPv6
Configuring IPv6 first-hop redundancy with MikroTik VRRPv3: troubleshooting Router Advertisement issues where IPv6 sessions died during failover, solving by disabling RA on VLAN interfaces and configuring IPv6 ND settings for proper virtual gateway operation.ipquail-go
Rewriting ipquail.com in Go using pilu/traffic router: replacing SSI/Apache hacks with proper API endpoints for IP/PTR lookups, nginx reverse proxy handling IPv4/IPv6 termination, and JSON response formatting.Nagios and IPv6
Implementing IPv6 monitoring in Nagios: creating dual-stack service checks with -4/-6 flags, defining custom _ADDRESS4/_ADDRESS6 variables for DNS independence, and navigating IPv4-only plugin limitations like check_icmp.Using ULA and NAT66
Implementing IPv6 Unique Local Addresses (RFC4193) with OpenBSD NAT66: generating fd00::/8 ULA prefixes, translating to public IPs, and workarounds for single /64 provider limitations or private VPS networks.Sleep Talking
Troubleshooting Intel I217-LM NIC bug causing 3300 pps IPv6 multicast storms during S1 sleep: using tcpdump/Wireshark to identify MLDv2 listener reports flooding network, resolved with driver v19.5 update.Troubleshooting ICMPv6 with tcpdump
Fixing OpenBSD PF firewall ICMPv6 rules by using tcpdump to identify required neighbor discovery types (133-137): isolating NDP traffic with packet filters and properly allowing router/neighbor solicitation/advertisement messages.IP Quail API
Building a JSON API for ipquail.com using Python/Flask and uWSGI/nginx: RESTful endpoints returning IPv4/IPv6 addresses, inspired by ARIN's Whois-RWS, with CORS support and production SSI implementation.ARIN on the Road
Attending ARIN on the Road in Winnipeg: IPv6-focused presentations, hands-on with RESTful web services API, discussions on DNSSEC/RPKI implementation, and networking with ARIN leadership.Fully IPv6 Enabled
Personal milestone: all public-facing services now dual-stack IPv6—anycast web, mail (SMTP/IMAP/POP3), DNS (authoritative/recursive), SSH/FTP, SSL VPN, SaltStack, Nagios, plus native home connectivity via HE tunnel.ipquail now curl friendly
Adding CLI-friendly IP detection to ipquail.com: returns plain IPv4/IPv6 addresses when accessed via curl, with separate subdomains for protocol-specific queries and script integration.VM Moves
Moving services out of the basement into a half-cabinet: OpenBSD edge router advertising IPv4/IPv6 space, ESXi host for VMs, Cisco switching, APC UPS, and initial site/monitoring DNS migrations.Selling IPv6 to Management
Business case for IPv6 adoption: criticality of Internet services, IPv4 exhaustion risks, deployment timelines, and presenting benefits to management with real-world considerations.IPv6 Task Force
Local IPv6 advocacy group at SkullSpace hackerspace working to raise awareness through IPv6-only demos, whitepapers, and real-world infrastructure setup between multiple locations.My IPv6 Services
Overview of native IPv6-enabled services including web (nginx/Apache), email (Postfix/Dovecot), XMPP (Prosody), and DNS. Covers configuration and operational challenges.2014: IPv6 and HTML5
Blog engine migration to Octopress with Markdown support. Upcoming technical articles on OpenBGPD looking glasses, IPv6 implementation, and infrastructure projects for 2014.RFC3021: 31-Bit Prefixes on PtP Links
Using RFC3021 /31 netmasks on point-to-point links to conserve IPv4 addresses. Comparison with traditional /30 usage and device compatibility notes for Cisco and MikroTik equipment.I'm doing AnyCast!
Setting up anycast services using Bird OSPF to inject /32 and /128 routes across multiple locations. Using FreeBSD VMs for redundant IPv4/IPv6 anycast DNS and web services.IPv6 Implementation Experiences
Personal experiences with IPv6 adoption from 2001 tunnel access through ISP-level deployment. Covers client behavior (Happy Eyes), NAT implications, security considerations, and network implementation perspectives.OSPF and IPv6
Configuring OSPFv3 for redundant IPv6 routing on Cisco routers. Covers unicast routing setup, OSPF processes, VLAN configuration, and IPv6 ACLs for secure SSH access.Which Sites ARE IPv6 Enabled?
Overview of major websites with IPv6 support including Google, Facebook, Yahoo, and Cloudflare. Browser extensions like IPvFox and ipvfoo help identify IPv6-enabled sites.Enabling IPv6 on Cisco 3560/3750
Step-by-step guide to enabling full IPv6 support on Cisco Catalyst 3560/3750 switches, including SDM mode configuration, unicast routing, and interface addressing setup.
