About the AT&T IP range data

ASNs and holders
AT&T announces its prefixes from AS7018. Holders in the registry: AS7018 (ATT-INTERNET4 - AT&T Enterprises, LLC).
What the list contains
The ranges are the prefixes these ASNs announce in the public BGP routing table (obtained through RIPEstat), with adjacent blocks left unmerged. This is not an ownership record: it can include prefixes of customers and leased address space, and it can miss routes that very few peers see. Snapshot of 2026-11-02.
Typical uses
Allow or block traffic from AT&T in a firewall, WAF or nginx, label source IPs in your logs by network, or test with a CIDR match whether an IP belongs to AT&T. Remember that cloud and carrier address space also runs the services of customers, so blocking a whole network can hit unrelated sites.

How to use the AT&T IP list

Start with the tables above: one for IPv4 and one for IPv6, each row with CIDR, start IP – end IP and address count.
Choose Download TXT or Download CSV for the complete list. The file has all 638 ranges, not only the first rows shown on the page.
Import the TXT as one address set into your firewall, router or ipset, or paste the CIDRs into a cloud security group rule.
Check the snapshot date (2026-11-02) before using it in production. Cloud ranges change often, so compare with the official range file published by the provider.

AT&T IP ranges: frequently asked questions

How many IP ranges does AT&T have?

As of 2026-11-02, AT&T announces 624 IPv4 prefixes covering 96,428,800 addresses and 14 IPv6 prefixes in the public BGP routing table, through AS7018.

What is the ASN of AT&T?

AT&T uses AS7018. Holders in the registry: AS7018 (ATT-INTERNET4 - AT&T Enterprises, LLC). Large organisations often run several ASNs, and this page merges the ones listed here.

How do I use the AT&T IP list for a firewall allowlist or blocklist?

Download the TXT file (one CIDR per line) and import it into ipset, nftables, an nginx allow or deny include, a router address list or a cloud security group. Import the 638 ranges as one address set rather than as separate rules. The address space of AT&T also hosts the services of its customers, so blocking all of it can cut off unrelated sites.

How often is the AT&T IP list updated?

The list is a snapshot of 2026-11-02, regenerated about once a week from public BGP data (RIPEstat). Announcements change every day, so download it again before using it in production, and for cloud providers also compare it with the official range file they publish.
