DNS NTT IPV6

EEnes · 11 nov 2022

Buongiorno a tutti,
Attualmente uso i DNS di NTT (ipv4) con cui mi sto trovando bene soprattutto lato gaming, (Cod/Warzone) usandoli ho notato una netta diminuzione del ping a livello matchmaking (40ms) rispetto a tutti i DNS o a quelli di default di PF (Google e cloudflare) 50/55 ms.
Volevo usare i rispettivi DNS anche su IPv6 e gli ho trovati:
2001:418:3ff::53
2001:418:3ff::1:53
il problema è che rispondono della Germania (Francoforte?).
Possibile che i DNS ipv4 rispondono da Milano e la loro controparte IPv6 in Germania?
Ho notato anche che da un mesetto i DNS di quad9 adesso rispondono da Milano. Grazie per ogni possibile chiarimento

Enes mi sa che viene usato HE in IPv6 invece che il transit NTT...

EEnes · 11 nov 2022

MN00AA ho controllato passa per NTT de

Buongiorno a tutti! Sapreste dirmi di più riguardo questi DNS? Voi li avete impostati sul dispositivo o direttamente dal modem? E quali sono i vantaggi?

MMN00AA · 11 nov 2022

Enes no sta passando per HE appunto, e' che non si vede perche' HE fa ICMP rate limiting molto pesante, sarebbero quelle richieste scadute. Poi HE ti porta da NTT in Germania appunto.

GiaNN · 11 nov 2022

Enes non capisco come possano essere collegati dns e ping in gioco...

DeltaFoxtMike i vantaggi generalmente sono una maggiore privacy di alcuni rispetto ad altri, ad esempio ora che quad9 risponde da Settimo Milanese non capisco il senso di usare cloudfare o Google che sono molto più invasivi della privacy.
Poi c'è anche la questione DNSSEC, protezione dai malware e altri servizi che certi DNS offrono mentre altri no.
@PF-Matteo visto che ci sono, come mai avete scelto cloudfare e Google invece che altro? O invece che farne uno interno per PF?

EEnes · 11 nov 2022

GiaNN non ne ho la minima idea, ma la noto solo con Cod su altri giochi dove puoi scegliere i server di gioco non cambia assolutamente nulla, magari può essere che Cod ha molti server sparsi per tutta Europa e scelga le lobby in base al DNS (sto ipotizzando da ignorante in materia). Su Warzone quando avevo Wind3 mettevo i DNS di level 3 che rispondevano da Francoforte e puntualmente mi metteva su server tedeschi, invece con i DNS Wind3 nei server finlandesi
Bella come idea DNS di PF

EEnes · 11 nov 2022

MN00AA ah, si potrebbe modificare il percorso per farli rispondere da Milano come i server ipv4? Come con i quad9

GGiacomo C · 11 nov 2022

Enes Ciao,
potresti dirmi i DNS ipv4 di NTT....Grazie.....

MMN00AA · 11 nov 2022

Enes si' ma deve farlo @PF-Matteo

MMN00AA · 11 nov 2022

Giacomo C 129.250.35.250 e 129.250.35.251

GGiacomo C · 11 nov 2022

MN00AA Grazie...molto gentile....

EEnes · 11 nov 2022

MN00AA lo spero prima o poi

PF-Matteo · 11 nov 2022

Mandatemi mail con i dns e lo faccio controllare lunedì o martedì

EEnes · 12 nov 2022

PF-Matteo fatto

PF-Matteo · 12 nov 2022

Enes spostato su NTT, ma ho il sospetto che non siano realmente a Milano i DNS, ma siano, come li vede Hurricane, in germania

@caldera1 ~]# traceroute -A 2001:418:3ff::53 traceroute to 2001:418:3ff::53 (2001:418:3ff::53), 30 hops max, 40 byte packets 1 (2a02:29e0:1:2::1) [AS49367] 1.432 ms 1.407 ms 1.390 ms 2 (2a02:29e0:255::e) [AS49367] 0.207 ms 0.194 ms 0.178 ms 3 ae-27.r00.mlanit02.it.bb.gin.ntt.net (2001:728:0:5000::1696) [AS2914] 14.410 ms 14.399 ms 14.617 ms

Come vedete anche se dice Milano, la latenza va da 0 a 14ms, quindi è palese che va in Germania

EEnes · 12 nov 2022

PF-Matteo peccato, grazie lo stesso Matteo

EEnes · 12 nov 2022

PF-Matteo Matteo scusa ma sono curioso, avete in mente di creare i vostri server DNS targati PF? In un futuro prossimo

PF-Matteo · 12 nov 2022

Enes Non so dirti, non ho evidenza di questa parte, non è gestita direttamente da me

MMN00AA · 13 nov 2022

PF-Matteo i DNS di NTT Anycast sono in Italia anche per IPv6, e' che per il ritorno NTT passa addirittura da Cogent poi ha come alternato solo HE, e non sembrano esserci rotte dirette...
