How this service works
Is this IPv4 address listed on ivmsip (sip.invaluement.com)? Performs the DNSBL query (reversed octets under sip.invaluement.com, via Cloudflare DoH) and returns listed yes/no with the return codes and, where the list publishes one, the reason text. One list, one precise answer. $0.01 per lookup.
Output
Returns whether the queried IPv4 address is listed on sip.invaluement.com, the specific DNSBL return code(s) associated with the listing, and any human-readable reason text published by the list for that IP.
Example use cases
Screen inbound SIP call source
“Is 198.51.100.22 listed on the ivmsip DNSBL? I want to know if this IP is flagged as a SIP spammer on sip.invaluement.com before allowing it to register on my PBX.”
Email server IP reputation check
“Can you check whether 203.0.113.77 shows up on the Invaluement ivmsip blacklist and give me the return code and any reason text the list provides?”
Investigate suspicious VoIP traffic source
“I'm seeing a lot of unexpected SIP traffic from 45.33.32.156 — is that IP listed on sip.invaluement.com's DNSBL, and if so, what reason does invaluement give?”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/ip/blacklist/ivmsip?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a precise, single-list lookup against the Invaluement SIP (sip.invaluement.com) blacklist specifically — ideal for SIP/VoIP spam filtering, telephony security, or when you need the exact return codes and reason text from this particular DNSBL rather than a multi-list aggregate score.
Side effects
- Invalid or non-routable IPv4 address provided returns an error or undefined result
- DNS resolution failure via Cloudflare DoH may cause lookup timeout
- IPv6 addresses are not supported (IPv4 only)
- IP not listed returns a clean/not-listed result with no reason text
- Transient network errors may cause intermittent failures
