AS25400 announces 79 IPv4 prefixes covering 1,567,744 addresses and 11 IPv6 prefixes.

About this network

The AS handle TELIA-NORWAY-AS is held by Telia Norge AS.

What it's used for

• The address space carries mobile and residential access traffic, evidenced by reverse DNS names such as connect.netcom.no and get.no, and netnames like NO-TELE1.
• With 1,633,280 IPv4 addresses announced across 106 prefixes and 44 observed neighbours, the high address-to-neighbour ratio indicates a large-scale access network serving end-users rather than a transit provider.

Notable

• Registrants for the majority of prefixes are Telia Norge AS or NetCom GSM Hostmaster, consistent with the announcer; however, some prefixes like 138.62.0.0/16 (netname NSB-NET) and 139.145.0.0/16 (netname AKER-STORD) have unknown registrants, suggesting historical allocations or leased space.
• Telia Norge is the result of the merger between TeliaSonera’s Norwegian operations and NetCom, which is reflected in the mixed Telia and NetCom branding in the reverse DNS and registrant data.
• The inventory includes a mix of large /13 and /16 blocks alongside smaller /17 and /18 prefixes, indicating a mature, subdivided address estate.
