DNS NTT IPV6

MN00AA

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

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?

Enes

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

Enes

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

MN00AA

Enes si' ma deve farlo @PF-Matteo 😅

Giacomo C

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

MN00AA

Giacomo C 129.250.35.250 e 129.250.35.251

Enes

MN00AA lo spero prima o poi 🤣

Giacomo C

MN00AA Grazie...molto gentile....

PF-Matteo

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

Enes

PF-Matteo fatto

PF-Matteo

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

Enes

PF-Matteo peccato, grazie lo stesso Matteo 👍

Enes

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

MN00AA

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...

PF-Matteo

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

PF-Matteo

MN00AA risponde un reverse chiamato mil, ma non rispondono quelli di Milano, infatti la modifica è già stata fatta. Sopra vedi il traceroute post modifica

MN00AA

PF-Matteo ciao, ti confermo che il server NTT Anycast che sta rispondendo e' effettivamente quello italiano a Milano adesso, in uscita va diretto verso NTT dal transito di Milano. Il problema resta pero' nel routing inverso, per qualche motivo mancano gli annunci diretti delle subnet IPv6 di SeFlow verso NTT e quindi NTT spara il ritorno tramite le uniche strade possibili ossia Cogent (preferito) o HE, ed entrambi fanno peering con NTT solo in Germania:
