Deep Whois is the most complete and advanced WHOIS app with whois history, change tracking and notifications. The tool lets you lookup info in ALL WHOIS databases for ALL hostnames, domains, TLDs, web sites, IDNs, IP addresses (both IPv4 and IPv6), IP network ranges and autonomous systems (ASNs, ISP IDs).

Deep Whois works out of the box and finds ownership, country and more info about everything with no need to mess with complex options and server selection.

- WHOIS domains, IP addresses, ranges, IDNs and ASNs
- Supports ALL domain zones, TLDs, IDNs known to date
- Supports IPv4 and IPv6 addresses and networks
- Support ARIN, RIPE, APNIC, LACNIC, AFRINIC and referral servers

What’s New

Version 1.17

- (seamless) RDAP support for domains where Whois no longer works
- monitoring with notifications for most of RDAP-only domains (such as .MS)
- monitoring with notifications for domains that have neither Whois nor RDAP (such as .TO), but have domain data available via the Privacy Shield service (query with the Privacy Shield enabled to verify and to turn on monitoring)
- improved query parsing: URL links and email addresses can now be used as queries directly without a need to copy domain names
- (automatically) connect to a fastest (nearest to you) Whois server for domains with multiple physical Whois servers (such as .UA)
- .JP and .TR domains Whois is now using Unicode
- most up to date Whois and RDAP servers for all TLDs and SLDs

For those users that do not need Pro services (historical and privacy Whois, monitoring with notifications) the Deep Whois Plus lifetime unlock is now available as a one-time permanent purchase at the introductory discounted price – choose "See all plans" at the bottom of the subscription screen to purchase.

New features that require a significant implementation effort (such as upcoming color theme and color customization support) will only be available as a part of either Deep Whois Plus permanent lifetime purchase or Deep Whois Pro subscription.

Features previously available free of charge will stay available for free.

Its That End User Again ,

Does it's thing. I use it for my Whois needs.

Sometimes iPhones get funky. Sometimes you catch network traffic that makes you go "huh?". Or sometimes you see a domain name and go "really?". Or sometimes you see an IP and.... you get the point.

This will suit your Whois needs.

Cost me .99 to download

I use this app to investigate different IP’s related to my content. Yet once in awhile like tonight (New Years 2022) it stated I don’t have access! For something I pay monthly for. Something I can’t log in or even make an account. I find that to be a subversive behavior. So who has access then if users like myself can’t even register with the app? Who are you to tell me I have no access when nobody at your platform has credentials like I do? Nobody at your platform has legitimate records for CVE, penetration testing, beaten federal jackets, ranked in the top 50 of CVE tickets and user who seeks the truth. So tonight I deleted the app. This is the game you want to play cool. If making money is your business plan. Your not really making money when people who pay for the app walks away. So to those who like the ability to access information to vector data. I suggest you don’t use this app. I personally resent the fact you say I have no access, yet have zero ways to register for said services. So keep discriminated against “paying users” let’s see if you about anything other then role playing god.

Developer Response ,

1) as a network pro you should understand that whois servers may become inaccessible or your IP can be restricted and that's not the app issue.

however, since now there is a pro service available for pro users. you can access whois via the build in Privacy Shield service overcoming IP address limits in most cases.

2) the first subscription in the app has been introduced on 2023-10-24, so might be you have mixed it with some other app...

p.s. contacting me directly via the support link would be much faster - this message I've seen today for the 1st time - in almost two years =)

Able to counter a hacker.

Because a hacker was trying to get into my accounts, I saw emails that told me where it was coming from, and it gave me an IP address which is where this app came into clutch because I was able to to locate where it was able to link to my accounts, and from there I could block it.
