EE 5GEE IP address ranges

[sphudson]

Hi,

Is there any info available on what IP address ranges are allocated to data only sims in 5GEE routers?

I need to connect to a secured environment, and as EE don't offer fixed IP's, the vendor will consider opening up the EE ranges.

I'm currently on 31.94.5.2**

That public IP is part of the EE pool:

IP  Location       United Kingdom United Kingdom Haringey Ee Limited
ASN                    United Kingdom AS2856 BT-UK-AS BTnet UK Regional network, GB (registered Dec 22, 1993)
Whois Server    whois.ripe.net
IP Address        31.94.5.2**
inetnum:           31.64.0.0 - 31.127.255.255
netname:         UK-TM-20101125
country:           GB
org:                  ORG-TIUL1-RIPE
admin-c:        TMUK-RIPE
tech-c:            TMUK-RIPE

Noted, but surely the range supplied to 5GEE devices, or off specific towers is a bit narrower?

EE has numerous pools of public IPs. Furthermore the EE mobile network uses Carrier Grade NAT (CGNAT) resulting in a double NAT, which games consoles often object to, which means you don't get your own public IP address but share it with other users. So you can't be uniquely id'ed on the Net & therefore your LAN cannot be addressed from outside for unsolicited accesses. This is unlike fixed BB. 

EDIT: Redacted that which is not relevant to your enquiry.

I am not looking to address my device or access it from an external network, I am merely trying to narrow down a set of IP addresses that an external firewall can allow through (as possibly representing my network)
