Asia Runs Out of IPv4 Addresses

The Asia Pacific Network Information Centre (APNIC) has announced that has reached stage three or final stage of IPv4 exhaustion in Asia Pacific, which means that it has released almost all of Internet Protocol version 4 (IPv4) addresses in its available pool.

IPv4 Exhaustion Stage 3 starts when APNIC reaches its last /8 of available IPv4 address space. At this stage, all new and existing APNIC account holders will be allotted a maximum allocation of a /22 from the Final /8 address space.

APNIC has said that it will prioritize new entrants and those deploying IPv6 for remaining IPv4 addresses.

This way Asia Pacific has become the first region to reach this stage of exhaustion, due to notably high telephony and internet growth and hence the demand for IPs in the region.

Last year, PTA had estimated that IPv4 addresses in Pakistan will exhaust in 2014, which now looks little incorrect, based on above mentioned facts.

APNIC and PTA have been encouraging ISPs to move their systems to IPv6, however, the progress in this regard (in Pakistan) is not very impressive. This marks as a warning call for all ISPs in the country to speed up their pace for moving to IPv6 addresses.

  • A very useful post. Will it in any affect those having a domain in their name? What if the domain is to expire say in 6 months time? Any comments?

  • “Last year, PTA had estimated that IPv4 addresses in Pakistan will exhaust in 2014, which now looks little incorrect, based on above mentioned facts.”

    PTA is correct! APNIC is running out of IPv4 but ISPs of Pakistan have already bought huge pools of IPs from APNIC for near future needs.

    Like, the following IP pools are currently allocated for PTCL:

    119.152.0.0 – 119.159.255.255
    116.71.0.0 – 116.71.255.255
    59.103.0.0 – 59.103.255.255
    182.177.0.0 – 182.177.255.255
    203.99.160.0 – 203.99.191.255
    221.120.192.0 – 221.120.255.255
    202.125.128.0 – 202.125.159.255
    203.135.0.0 – 203.135.63.255
    (plus a fews others I don’t remember)

    These pools sum to approx. 1 million IP addresses while PTCL currently has approx. 0.4 customers.

    The same with other ISPs..

    It will take years for Pakistan to run out of IPv4 addresses.

    • Yes, we do have enough IPv4 pool, however, this fact should never be used as an excuse for slow transition to IPv6
