What are some online network tools that you use?

MannDude · June 2022

For example, for over ten years now, I've used https://intodns.com for quick reference of things like a domain's nameservers, A record or MX records. I know there have to be more modern and informative tools.

I also find myself using things like https://mtr.sh/ , https://ping.pe/ or things like https://www.whatsmydns.net/ frequently.

And then you've got things like https://bgp.he.net and https://bgp.tools/ and https://rpki.cloudflare.com/

Can we get a halfway decent list of useful online tools?

For me, it's 1.1.1.1 because a lot of time need to check if DNS is working

https://whois.ws - quick check for domain information with /whois/domain.com
https://ipinfo.io - ip information

I use dnstools.ws and been waiting for IN worker for a very long time.

https://tools.bunny.net also comes in handy quite often.

Logano · June 2022

I have the downloadable WinMTR on all my computers, and iplocation.io is a permanently open tab in my phone's Chrome.

dns.google

Ympker · June 2022

I frequently check:

https://infobyip.com

https://ipleak.net

Call me old, but I still use Unix commands, like: ping, mtr, dig, whois, nmap

The only exception is ipinfo.io which I rarely use for more details about some providers.

As a side note: I still love Linux Mint MATE.
F*ck Windows and all it's bloatware.

Same, but most these tools will check against multiple locations. Unless you've got a couple dozen geographically diverse servers, it's nice to get results from multiple sources, especially for DNS related stuff or MTRs.

https://ping.sx

rcy026 · June 2022

Most of the time I just use the command line versions of ping, mtr, whois etc, but one tool that I have found useful several times is https://zonemaster.iis.se/en/. It makes it so easy to verify correct delegation and propagation.

intodns - as previously mentioned.
mxtoolbox.com - not just for MX records.
whatismyipaddress.com - confirm working VPN, plus trace those feckers that port scan/probe etc.
https://www.ssllabs.com/ssltest/ - admittedly, not used much recently.

xVPSx · June 2022

https://observatory.mozilla.org/
https://cryptcheck.fr/

Some of my used tools in addition to already mentioned:
https://dnschecker.org/ - DNS
https://viewdns.info - all around tool
https://crt.sh - ssl/tls certificates

Domain specific
https://host.io - domain details
https://gwhois.org - whois
http://hosterstats.com/ - domain history
https://whoisrequest.com/history/ - another domain history

curl ifconfig.co / curl ifconfig.me - quick VM public IP lookup

for ping latency, I use mostly mtr.sh or ping.pe, at times https://www.globaltraceroute.com/ if I need a more exotic location (thank you @rm_ for sharing the tool last year! )

https://getipintel.net

For getting my public IP, I use https://icanhazip.com/ - It's curl/wget friendly which is really great for scripting & command line usage.

I also like checking RDNS sometimes; I use https://remote.12dt.com/ for this.

DNSTools India node should be coming back soon

Edit: should be back now.

dnstools.ws can do reverse DNS using the DNS lookup option if you select PTR as the record type, but maybe I should make it clearer in the UI? It used to have a separate "Reverse DNS" option but I removed it to make room for the MTR feature.
