Fix duplicate IPv6 addresses: Remove Verisign entries

claude[bot] · Panchajanya1999 · claude[bot] · commit 6fd7ebcebaa3 · 2025-10-06T15:53:55.000Z
Verisign does not offer public IPv6 DNS resolvers. The addresses
2620:74:1b::1:1 and 2620:74:1c::2:2 are Neustar's UltraDNS IPv6
addresses, causing duplicate entries in the DNS server list.

Removed Verisign IPv6 entries from both pingerr.sh and pingerr_ash.sh
to eliminate redundant testing and prevent misleading results.
