Authoritative DNS v4 vs v6 traffic breakdown by POP (30-day average)

Authoritative DNS: IPv4 vs IPv6 Traffic Breakdown by POP

Time range: 30-day average (increase[30d] / 2,592,000s)
Data source: Victoria Metrics via MCP — pdns_auth_*_queries counters on datum-managed-auth-dns
Timestamp: 2026-07-13T20:15 UTC

How It's Computed

PowerDNS auth exposes four cumulative COUNTER metrics:

Metric Meaning
pdns_auth_udp4_queries Total UDP queries received over IPv4
pdns_auth_udp6_queries Total UDP queries received over IPv6
pdns_auth_tcp4_queries Total TCP queries received over IPv4
pdns_auth_tcp6_queries Total TCP queries received over IPv6

Average queries/sec over 30 days:

sum by (cluster) (increase(pdns_auth_udp4_queries[30d]) + increase(pdns_auth_tcp4_queries[30d])) / 2592000

Same for v6. Then v4% = v4 / (v4 + v6) * 100.

Global Totals

Protocol Avg Queries/sec Share
UDP v4 58.55 82.3%
UDP v6 12.60 17.7%
TCP v4 ~0
TCP v6 ~0
Total 71.15 100%

TCP is negligible — all traffic is UDP.

Observations

  • No POP has majority v6 over the 30-day window
  • Highest v6 share: us-central-1 (29.6%) and us-east-1 (28.3%) — both US East/Central
  • Lowest v6 share: in-west-1 (5.4%), au-east-1 (6.7%), ca-east-1 (6.6%)
  • Highest absolute volume: us-east-1 (14.3 q/s), us-central-1 (9.6 q/s), de-central-1 (8.2 q/s)
  • The 5-minute instantaneous rate showed ~32% v6 vs 18% monthly average, indicating IPv6 DNS traffic is growing

Notes

  • prod-infrastructure-control-plane and us-central-1-lab show zero query volume (control-plane/monitoring only, excluded)
  • Managed DNS (datum-managed-auth-dns) accounts for all meaningful query volume; dns-operator PowerDNS instances are near-zero
  • Each POP runs 2 replica pods; counters are summed across replicas per cluster
