Log retention
ISPs must keep subscriber session and usage records for two years.
Every RADIUS accounting record is archived for 25 months.
How it worksCompliance
DoT compliance for ISPs, handled by the same system that runs the network.
Neurix by i9 Network makes DoT compliance for ISPs part of daily operations: sessions and NAT logs are kept for two years, a lawful request for who held an IP is one search, KYC is captured at install, and GST e-invoices are raised as you bill.
Obligation by obligation
What the rules ask for, and what Neurix does.
Each obligation links to the part of Neurix that handles it.
IPDR and NAT logs
You must be able to show which subscriber used an IP and port at a given time.
NAT logs are stored and searchable by IPv4 address, IPv6 prefix and time.
How it worksLawful requests
Agencies ask who held an address, often months later.
One search returns the subscriber, session and NAS for any address and time in the retention window.
How it worksSubscriber KYC
Each connection needs identity proof and a signed customer application form.
The field app scans Aadhaar and PAN on the device and collects an Aadhaar e-Sign on the CAF.
How it worksGST invoicing
B2B invoices above the threshold need an IRN from the invoice registration portal.
Billing generates e-invoices with IRN, respects the 24-hour cancellation window and prepares GSTR-1 data.
How it worksData residency
Some ISPs must keep logs inside their own premises.
The log store can run on your own servers, so the logs do not leave your network.
How it worksQuestions
Compliance questions we get asked.
Is Neurix certified by DoT?
No software is certified in place of an ISP. The DoT sets the obligations for licensed ISPs; Neurix gives you the records and tools to meet them, and compliance with your licence stays your responsibility.
How long is data kept?
RADIUS session records are archived for 25 months and IPDR NAT logs for two years, which covers the DoT's two-year retention requirement.
Can logs stay on our own servers?
Yes. The log store can run on-premises, so the data never leaves your network.
What do we need to answer a lawful IP request?
The public IP (and port, if CGNAT is used) and the date and time. Neurix returns the subscriber, the session and the NAS that held the address.
Does Neurix keep KYC documents?
The field app captures Aadhaar and PAN details and the e-signed CAF against the subscriber, so each connection has its KYC on record.
